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.
TOTAL PRICE: ~$1030 (before MIRs) this is about where I want to be.
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.
I see no trouble with the build. But, if you want your system to be future proof for the next ~3 years, I'd go with the new DX11 generation of cards. That's totally preference though, if you're fine running on DX10, your build's good.
I'm not sure about the size of the HD 4870s, but I've read somewhere that GPU size could be an issue in the Antec 300 case. Unsure about this though.
I'm doing the same thing as you, trying to get a build for ~$1000. I've been researching for three weeks now, and have yet to decide! There never seems to be any good future-proofing choice, things are always getting released .
