So essentially what your saying is that any card that isn't bottlenecked at PCI-E 1.1 in a single card is not going to be bottlenecked in a 8x8 PCI-E 2.0 setup. As from what I've heard, not many cards really push the PCI-E 1.1 bandwith atm. The best card I'm willing to buy at the moment is a 4850, will that hit the PCI-E 1.1 limit?
