PCI express *16 work with a 2.0 (*32) card? - Page 2

post #11 of 16
Thread Starter 
When I build my new system I'll put the 2.0 card in and put the 1.0 back in the old system. I've been playing COD4 and at max resolution it stutters. Thanks for all the replies.

The interface which graphics cards require has not yet reached the bandwidth provided even by pci-e yet alone pci-e 2.0. The upgrade to version 2.0 was to provide extra head room and more voltage.

You can run a card at 4x pci-e 2.0 (8x pci-e) (by covering up the relevant pins on the graphics card) and there will be no drop in performance. Only on the generation of cards yet to be released will there be a need for you to run at 8x pci-e 2.0 (or 16x pci-e).

Thats what i thourght..... so PCIE x16 1.0 still provides enough bandwidth to run any pcie 1 or 2 card without a lag in performance

I guess this is quite similar to the situation with AGP 4x and 8x. No real huge differences.

None of the 2.0 cards even use a full 1.X. Yes it will work. And it will be the same.
