Build Spec Review

^ this. three or four 7970s will do well with it though. but you need to make sure that case can handle four 7970s with the UD7. most can't.

Good point, most of the time, the bottom slot is too low to fit double/triple slot cards. I don't know how the motherboard sits in this case but it's likely that 4 GPUs will not work without some fiddling around with PCI-E extenders and probably an open case.
