~$1000 Gaming System, 2nd build

APPROXIMATE PURCHASE DATE: This week

BUDGET RANGE: ~$1000 before rebates

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming (Bioshock 2, Mass Effect 2, Modern Warfare 2, Diablo 3 etc.)

PARTS NOT REQUIRED: Keyboard, mouse, speakers, OS (I have Windows 7 Pro)

PREFERRED WEBSITE(S) FOR PARTS: newegg (open for other suggestions)

PARTS PREFERENCES: Generally prefer AMD/Radeon, but feel free to convince me otherwise.

OVERCLOCKING: Maybe (haven't done it before, but I'm technically capable)

SLI OR CROSSFIRE: Yes/Maybe

MONITOR RESOLUTION: 1920x1080 (This is what I'm shooting for, but I need the monitor still, and my graphics card(s) may be too much for this resolution?)

ADDITIONAL COMMENTS: I would like this machine to last ~3 years, and be able to adequately run the next generation of games. I'm not all that interested in top performance, but something that will get decent FPS. I'm not interested in DX11 features (although do your best to convince me if you feel so inclined). Crossfire may be overload, but I found a good combo deal with some 4870's and an adequate nice power supply. I'm open to lowering the price by getting a single GPU and a lower-end power supply.

Questions: I'm open to suggestions on the MOBO, and whether or not I actually want Crossfire. I found that combo deal with the 4870's and the power supply that seems pretty nice...other options may be to get a single GPU and a less expensive MOBO and PS, but I want this system to last at least 3 years. Convince me if you think I need to get the new DX11 card. Also, I'm looking for recommendations on monitors - the Dell seems to be decent for the price. I'd like to stay under $1000 total if possible. Feel free to recommend other builds or parts you think may be better. Also, let me know if there's going to by any bottlenecks or incompatibilities.


Thanks in advance for the help/advice!
