oh and, many "old games" probably are more relevant than some 5 hour newer games, how many still play WOW, CS, TF2, SC2 compared to Crysis 3?
Many of those games run fine on much older and cheaper CPUs and graphics cards anyway,and their cartoony art style is such that you can turn down settings without a massive visual impact also. This is why tens of millions of people play them. WoW,CS,TF2 and SC2 will all run even on laptops. Blizzard and Valve make games which are as accessible to as many people as possible since they want as many users as possible. Even the Diablo series is making a return to consoles,so Blizzard can get even more sales.
Only on computer forums would an overclocked Core i5,Core i7 or FX8300 series CPU be needed to run them.
oh please, you don't need, but the i5 will run faster, people here buy expensive graphics cards, and you ignore the huge difference a CPU can make on older (and newer) games...
go play most mmos/rts, it's awfully CPU bottlenecked, but hey, you can play at 15-20fps with old hardware, sure, a lot of people do that.
and always keep in mind, these benchmarks are made on quick runs, it's impossible to represent well the entire game, so on the ideal world people will at least test "bad spots" in the game and have a lot of GPU power, but that's not always what happen... a simple example is BF3 vs BF3 MP64...
You are also ignoring the fact that millions of players of these games are not having overclocked Core i5,Core i7 or FX8300 series CPUs.
I know loads of people who play these games ,loads and some in reasonable sized clans(the types which also have meet ups in person at times too).
Very few have top end hardware like Core i5,Core i7 or even the best AMD FX8300 CPUs. If all games needed that level of performance than the PC gaming market would dead,for 95% of all players.
Most gamers are not hardware enthusiasts and from my own experience have no issues turning down a few settings anyway. You talk about TF2,I have run that fine on my backup rig wich has Core2 level CPU performance during big battles(Saxton Hale maps) with loads of players crowded into one area,and performance was fine. The best SC2 player I met was running an old Phenom II X4,and was in the Diamond League too.
If anything a reasonable internet connection is what you probably need more in many cases.
Reviews probably overstate the hardware needed in many cases IMHO. You can look at reviews which test things like audio encodes. What they don't tell you is that they first rip the CD to wav and then plonk the wav file on a SSD or in a RAM disk,to remove the biggest bottleneck,ie, the optical drive used. The vast majority of people will just rip a CD on the fly from the optical drive.
Edit to post.
By also overstating the entry cost of gaming on forums,we are pushing more and more people to consoles due to their lower upfront costs,lack of needing to upgrade hardware and long lifespans.
Getting more gamers onboard, even with budget PC hardware, is what we should be doing so we get more PC exclusives rather than modded console releases.
