I currently have 2x HD5770 in crossfire running 3 monitor with res 6036x1080 (w/ bez comp). I frown at this setup because the 5770 can't handle the eyefinity setup. I need to set almost all my games to low or lowest resolution in order to play it. If I disable the eyefinity and just use a single monitor (1920x1080) then everything runs perfectly fine, even at ultra/highest setting. I also dislike crossfire or SLI because my mobo's pci slots are too close together, which makes the top card run about ~18C hotter then the lower card.
My questions is:
What is the minimum single ATI card solution I would need in order to run eyefinity at highest setting, such as BC2, WM3, BF3, Black Ops, etc.?
Also keep in mind I like to install and run IZ3D drivers, which with my current setup will automatically drop my fps down by 10 simply by installing the drivers. If I enable the 3D feature, my fps drops another 35 in eyefinity.
