Newegg is great for builds, I buy the vast majority of my parts from them (even though they just started charging me sales tax because I am in NY). However, anyone who is trying to do a build on the cheap and still want stop performance, needs to consider ebay as a primary source. Look at the systems I posted below. If I went all retail, they would have been over $3,000. Ebay rocks, especially with CPU's. If a cpu works, it works. I never got one that only ran at 1/2 speed or only on one core . Used chips are every bit as good as new chips if they work at all. As far as buying a processor that had been overclocked, the life of the chip may be reduced, but it more than likely will survive longer than you are going to use it. Besides, most of the used part purchases are sed for 6 months or less on cutting edge parts. I won't pay more than $100 for a E6300 and I won't pay more than $150 for a Q6600. And that happens on ebay. sort by completed listings and check it out. Heck I even got my QX9650 for $800 new in retail box three months ago. They still sell for more than that. Check out these build, they both work great:
