Geforce Nvidia GTX 570 is the only high market card that I have seen with pci-e 2.0. My motherboard supports no higher then pci-e 2.0, So this wouldn't cause bottle necking would it? Currently I have a Nvidia GT 210 and want to upgrade to the maximum for my motherboard and CPU which is an Intel Core 2 Duo 8400 3.0 GHz. Thank You
