I have to ask one question. Why? There is no need for that much. I run @ 5040x1050 and I have 1 HD6990 4GB. I can run any game currently on the market on full ultra settings without any issues. Your 6990 + 6970 is already overkill as it is, I would use your money on a custom liquid build

To answer your question, Both the 6970 and 7970 use ~250 watts per card, where as a 6990 uses ~375. Granted, this is not under full load (which you wouldn't be)

Your 1200w should be plenty, so I see no reason to up that either. Good Luck!

Well I have 7970 in corssfire running 5760 x 1080.

I'm thinking of going 3 x 7970, simply because there are games I play that have FPS drop, Crysis 2, Far Cry3, and one that surprises me ... WarZ and DayZ
