- How demanding are the 3-D apps you run ? If they demand a lot, I would suggest two 5970's in CFX...but I may be living my dream
. If you don't need two 5970's, then two 5850's in CFX would probably be enough (One is almost overkill). If you dislike ATI, the GTX 275/285 would hold up until the 300's are released.
- For the CPU, i7 920 and a good aftermarket cooler for OC (e.g. TRUE, Megahalem, Noctua NH-U12P, or something of the sort (for air cooling), or a H50 if you like a simple cpu watercooled setup, anything advanced for watercooling you'd have to ask someone else =[ ).
- For the RAM, I've seen a lot of recommendations for Mushkin/G.Skill ECO/OCZ (Amount is up to you, maybe ~12 gigs ?).
- For your motherboard, I am an ASUS fanboy (my buddy runs a P6T V2 Deluxe and he loves it), but again, I've heard great things about other brands (Gigabyte, EVGA X58, etc.) so that is entirely up to you.
- For the power supply (Run a calculator for the wattage, I can't think of an accurate number off the top of my head but I'd guess ~800), I would say a Corsair, but OCZ/Antec both make quality stuff.
- For the case, HAF 932 has great reviews as well as the Antec P183/193/etc. If you plan on CFX'ing the 5970's (Huge cards), a full tower would give you more room to work with. Also would have to consider your own aesthetics
.
- If you plan on air cooling, slap two Scythe Gentle Typhoons, but with that budget, I would 100% recommend watercooling. I don't know what kind of fans you would put on the radiator though.
- The rest is up to what pleases you
