So let me understand this correctly. PCI-E 2.0 x8 is not enough to run 5 times 1080p resolution using 4 cards that had an MSRP release price of 550 dollars? Mind=blown
Sorry for the sarcasm but it's assumed if you're gonna spend 4,000+ on a monitor and 2,000+ on a video card, you're going to be running a newer motherboard. And also getting 2% FPS increase going from DDR2 to DDR3 isn't mind blowing either.
