Oh, and a 750 watt Corsair power supply would be enough for crossfire 6850s/70s, right? This is probably going to be my last computer upgrade.
Games I most commonly play are:
Just Cause 2
Would crossfire support those games? Those are basically the few only games I own that I cannot max with my 4850.
I also considered waiting for the AMD Radeon 7xxx series, rumor has it that it will come out in Q2 of 2011 (in about 5 months) at a 28nm process, which I believe will just be the 6xxx series with a smaller die/whatever and more shaders, less power, less heat, etc. I mean, I CAN wait, I wouldn't really like to, but seeing how I'm crazy about value, the 7xxx series sounds amazing. Small nanometrics, higher yield, lower price, more crap on a the chip.
