BUDGET RANGE: 1100-900 dollars (Preferably this should be around the lower range; please help me improve the price with combos and rebates without losing performance).
SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming (Crysis), internet (to include AP high school courses that I am taking online), music.
PARTS NOT REQUIRED: OS, mouse, keyboard, speakers
PREFERRED WEBSITE(S) FOR PARTS: newegg.com
COUNTRY OF ORIGIN: U.S.
PARTS PREFERENCES: Probably Intel for gaming quality performance. For other parts I am uncertain and likely need help.
OVERCLOCKING: Yes, but please give me advice and links to guides in order to do so.
SLI OR CROSSFIRE: Perhaps if it is economical and improves performance.
MONITOR RESOLUTION: 1920x1080, but considering an upgrade later on.
ADDITIONAL COMMENTS: Thanks for the help everyone! I truly appreciate it and apologize if I am clueless (especially regarding the GPU). My chief concerns are compatibility, performance, and price. As I mentioned earlier, I am uncertain and need help; but here is a rough list I assembled after reading the Homebuilt PC Buying Guide:
CPU: You can cut to an overclocked AMD 955 (seeing your games are GPU intensive) and save yourself 50-60 on the CPU + motherboard. And if you're using an aftermarket cooler, then save $5-10 and buy the OEM
PSU: You don't need anywhere near 850W. For your build, 600W will do. And go Antec, Cooler Master or Thermaltake
Otherwise everything else looks awesome. Your chosen HSF is very good.
If you're still looking to trim down, an HD5850 can save you ~$50 and performs just below the 470...consumes far less power too.
edit: very hard to trim down. You've chosen an excellent price/performance build.
If you want to save $, do as L0tus suggested and go for AMD instead. I suggest the AMD Phenom II X4 955 & ASRock 870 Extreme3, and one HD 5850.
If you're going with the Core i5 750, I really feel you'll need the ASUS P7P55D-E Pro instead, it costs more but is worth it simply because the P55A-UD4P can't CrossFireX/SLI when you use SATA III/USB 3.0.
Save $20 and buy the CM Hyper 212 Plus from somewhere else, newegg is selling them at an inflated price right now.
Save money and go with the HD 5850 or GTX 460 (Core i5 system if you want to use the GTX 460, SLI later on) and you'll only need a 650W PSU which means you save even more $.
If so it appears to be in stock already. I have a question though: if I choose to stick with the Intel route and SLI later on with the GTX 460, how much will it improve performance? (Is it worth the extra $250?)
Just concerning performance, do you think that SLI is a better idea than AMD and a single card?
