When buying a replacement for my geforce 7950 gt, do i need to worry about the pci-e number? I know my slot is pci express x16, but don't know if 2 or 1 makes a difference. Thanks
It`ll make no real difference even if you`re going for a super fast X2 card in which case PCI-E 1.0 or 1.1 might take a few percent off the maximum speed.
Venom is correct, but it is a moot point as no card can currently use the full bandwidth of 1 you'll lose about 1-5% using a by using a 1.0 vs 2.0 ie only a benchmark would see the difference.
