Due to the number of Rate My Build threads, I decided to make this chart/list of components that are the cream of the crop at the particular price points to stop any confusion. Feel free to ask any questions or enlighten me if you feel any of these products are wrongly listed. Oh yeah, bump this thread if this thread has helped you.

Why are all the cpus AMD? Because dollar for dollar, AMDs will outperform any intel chip out today on the desktop market. Pentium 4s use a architecture called Netburst which means that it has low instructions per clock but very high pure megahertz rating. AMDs have a different architecture which executes many instructions per clock on a shorter pipeline for lower pure megahertz rating but higher performance overall. The difference is like a Semi Truck and a Corvette. The Corvette may seem faster but the Semi truck will transport the load of bricks much faster overall. Furthermore, AMD's X86-64 is more mature than EM64T and has a lot more 64bit programs that run on AMD's 64bitr architecture than Intel's. There is a third choice for 64bit called IA64(Intel Itanium only) which should not even be on any list if you are considering a home system to run normal programs on. There are about 3700 IA 64 applications, but unless CRM and SAS are words you use daily when doing home computing, 99.9% of those programs are worthless to you.
As for the debate between multicore and singlecore, Multicore is always better. Multicore is the wave of the future and programs are more and more cokmmonly supporting multicore. Sice CPUs arent all that critical for gaming, I would recommend a multicore if you can afford it. Multitasking just feels so much more smooth.

Ulltra High End Nforce4 Sli
ASUS A8N32-SLI Deluxe(Fanless since some users are really annoyed by the high pitched fan on other motherboards and allows both cards when in sli to run at full 16x speed. Really only need if you are using dual chip 4 way sli, otherwise the bandwith isn't really needed.)

------Socket 754
Value
Gigabyte GA-K8NE
ASUS K8N-VM Micro ATX(is smaller and less able for expansion but has onboard video)
Premium
Asus K8N4-E DELUXE
You may have other boards to add, but I chose these for their name brand, overclockability and features. Going with a company like ASUS or DFI means you cant lose. You know the boards will be reliable, good overclockers(as per reviews) and if anything goes wrong, you can easily go through the RMA process and get a board back if you are in warranty.
Micro ATX requires a case that supports microatx mounting points. They are less able to expand and offer less slots for cards usually.
Also, if you do go and buy the fanless A8N Sli Premium or A8N32SLI Deluxe, make sure you have a regualr ATX case, not some special case that mounts the motherboard upside down. Make sure the alrge heatsink is facing up not down.
Ram
Value Ram 1gb
CORSAIR ValueSelect 1GB (2 x 512MB)
Low Latency Ram 1gb(not recommended unless you have money to burn)
G.SKILL 1GB (2 x 512MB)
Value Ram 2GB
CORSAIR ValueSelect 2GB (2 x 1GB)(Better than G.Skill 2x1GB since it costs less and has a lifetime warranty, otherwise identical)
G.SKILL Value 2GB (2 x 1GB)(Use this for Some DFI boards since Corsair ValueSelect and certain DFI boards dont play well together)
Low Latency Ram 2GB(not recommended unless you have money to burn)
CORSAIR XMS 2GB (2 x 1GB)
Overclocking ram is not listed since overclocking is very YMMV(Your Mileage May Vary) and to be honest, AMD64s dont really care about bandwith. Latency affects performance more than bandwith but in general, unless you do a lot of encodig/decoding, ram will not make a real difference and ram is one of the worst performance upgrades you can spend money on dollar for performance dollar.

~Sky is the limit
SAPPHIRE Radeon X1900XTX
eVGA Geforce 7900GTX (About same speed as x1900xtx when compared in non sli. In SLI it will be faster than a 1900xtx in crossfire, but if you like high levels of AA, the X1900xt will be faster)
HTPC Graphics Card
MSI 7300GS
Sapphire X1300 (If you need dual dvi or fanless)
These are the general consensus cards out there.
Nvidia Drivers and ATI drivers are about on the same level. Many people complain about texture shimmering with Nvidia cards while ATI card drivers require .Net framework to be installed. As for the SM3 issue, SM3 allows many pretty effects like displacement mapping, parallax mapping and HDR lighting(most games need SM3 for HDR rendering, but some, like Half Life 2 and it's sibling games like Day of Defeat Source do not require SM3). As for why there is no high end HTPC cards, just pick a high end gaming card for your HTPC, but if you dont plant to do gaming on the HTPC, the two listed ill suffice.
There is a debate of SLI, Crossfire and Single Card. SLI/Crossfire should only be used when there is no single card solution to reach the speeds you want. A lower card in SLI/Crossfire like 6800gt or x1600XT are worthless since you could have the exact same amount of power with less heat dissapation, lower power requirements, and increased reliability(1 fan is more reliable than 2 fans just as 1 set of capacitors is mroe reliable than 2x as many capacitors). Also, some games do not support SLI or Crossifre and may gain no benefit at all from it.
If you decide to go dual card(as in Sli 7800gt/gtx or Crossfire x1900xtx), you shouldknow the advantages and disadvantages.
SLI:
*More mature and widely supported than crossfire. Also more efficent.
*Allows 16x aa
*Does not require a master card and external dongle for best performance. 2nd card must be identical card from the first though.
*Connector between cards in internal instead of external.
Crossfire:
*Allows 14x aa but is much faster than SLI aa. 14x aa is just barely slower than 4x aa, whereas, 8x or 16xaa on SLI will slow the game signifigantly compared to 4xaa.
*Does not need identical cards, The x1900series has a mastercard that can pair with any other x1900. It will clock itself to the correct speed and work.
*Getting more and more mature every day and the Crossfire motherboard I listed is the best motherboard money can buy right now. It is the best overclocking motherboard Anandtech has ever tested.
DVD Burner
Value:

High End
PLEXTOR Black IDE Slot Load(Style, nice for a HTPC so it blends in with the other components)
PLEXTOR Beige SATA DVD Burner Model PX-716SA/SW (if you've run out of ide channels)
These should be the cream of the crop. The NEC and BenQ should do basically as well as the plextor, but the plextors have special features no other (good)DVD drives have, like slot loading and SATA capability.
Cases(chosen based on cooling and quietness)
Value Case and Power Supply
Antec LifeStyle SONATA II Piano Black Computer Case With 450w power supply
Mid Level Case

High End Case
Lian Li Classical Silent PC-767 Silver/Black No PS
HTPC
SILVERSTONE LASCALA 10 CS-SST-LC10B Black(Value)
SILVERSTONE SST-LC01(High End)
Any case is mostly fine, but a better case wil be better laid out with easier upgrades, lower temps and quieter operation. You can go pratically any case and it will work but if you stick to this, you can get a solid case for many upgrades or new system builds to come. When buying a case, look for good airflow, big fans(bigger the better since bigger fans spin slower to move the same amount of air, thus being quieter) and a nice design you like. Also, make sure the steel edges are rolled ro buy an aluminum case. If the case is steel but the edges aren't rolled, you can easily cut yourself and it is quite painful since the cut is very similar to a papercut.
Power Supplies
Low End

This is an area where I could use the expertise of some people. The FSPs are nice low to mid end power supplies as are the Zippy. The PC&P are excellent(best bar none) power supplies, for a price that is. Of course, there are oher valid options like Seasonic(excellent mid to high end), Sparkle(a subcomapny of FSP/Fortron), Antec(some people have problems with new units messed up the first time it boots, but if it runs fine the first time, it's golden) and Enermax I beleive. Whay you should avoid are generic and Thermaltake(way overrates wattage rating), and Ultra/Xconnect(not very reliable). If you opted for the Valuecase with a psu, a additional psu shouldnt be necessary except in special situations where you need more power.

SATA and IDE are the same in performance. No harddrive can satureate a IDE channel yet so dont worry about that. he only advantage of SATA is that it has prettier wires.
Matrox tends to be low reliability compared to others, Seagate 7200.8 are also low reliablilty, otherwise the others will be fine. WD is faster, Samsung is quiet and cool, Seagate and Maxtor (same company now) are a balance between WD and Samsung.
Raid 0 is only useful for sustained transfers. Seek times are increased for higher sustained transfer rates so for normal use, Raid0 will either give you a marginal benefit or none at all or even a small decrease in performance. If oyu transfer many large files though Raid0 is worth it.
Raid 1 is worth it if you have critical information.
Raid 5 is damn expensive but offers the advantages and disadvantages of 1+0.
Hint: If you want to buy a HDD, do not buy from newegg, a retail store usually has big sales on HDDS. I hot 2 hitachi 7k250 160gb HDDs for $20 each on black friday. The only problem is if you want Samsung(which is my favorite brand). They are only available online and to pc builder companies(usually HP, sometimes Dell) and almost never go on sale.

A sound card should be proportional to the quality of your speakers. You shouldnt hook up some Logitech Z-5450, Creative GigaWorks S750, or Klipsch PROMEDIA ULTRA 5.1 to a onboard sound system but neither should yuo hook up some Cyber Acoustics CA-3090 2.1 to a Xfi Elite. As a general rule of thumb, 2.1 or less is fine with onboard but surround shound should really come from a dedicated music card. Of course there are obvious exceptions like if you want to enjoy some M-AUDIO StudioPro 4 2.0 Pro or Klipsch ProMedia 2.1, you should hook them up to the M-AUDIO 9900-40901-00 Sound Card or a Creative Sound Blaster Audigy2 ZS respectively.

High End LCD
Dell 34" 2405FPW
Ultra High End LCD
Dell 30" 3007FPW LCD(Needs Dual-link DVI Video Card)
In general, a well set up crt will alays be better than a well set up LCD. Blacks will be darker, Whites will be brighter, it iwll be able to adapt to different resolutions. LCDS have a native resolution( a set number of pixels horizontally and vertically) so it cannot as effectively represent other resolutions than native witouth a) an large image quality drop or b) a smaller image surrounded by black bars. CRTS can compensate since it has a large(though not infinite) number of phosphors to hit with the electron gun so any resolution will look good and sharp.
Now, the Dual Link DVI is a special connecotr that hugh resolutions monitors using DVI need because normal DVI dosent prvide enough bandwith. A single link is good up to 1920x1080 while a dual link is good up to 2048x1536. Dual link has 3 rows of 8 while Single link has 2 banks of 3 rows with 3 pins each seperated by a space 3 rows high and 2 pins wide. Some Video cards may support dual link and some only single link.
These are all my opinions so take it for what it's worth.
If you have any special needs like say a ultra cheap pc or a business pc or anything, feel free to post a request in here or PM me and i'll try to get back to you and help you.
The areas I feel I am not qulified to give an opinion on are TV tuners(lack of knowledge) and peripherals(I will give an opinion, buit with mice/keyboards, it's mostly personal preference and ergonomics that determine it).
