Awhile back I asked a similar question, now that its official that the newer AMD boards will have SLI support I should ask again. Currently my setup is 2 x 285GTX cards in SLI with watercooling.
How would a single 580 compare? They are approx $500 USD each and another $130 for the full sized waterblock, I'm looking to get my money's worth here. Currently my 2x285's run everything just fine with 1920x1080x120hz (Nvidia 3D Vision). What games are on the horizon that could possible tax my current setup and require an upgrade? I'm mostly into RPGs and rarely venture into 3D FPS (I enjoyed Battlefield 2 but hated CoD MW).
