Will a graphics card with pcie 2 0 lose any performance when plugged into a pcie
Hello, i am looking at buying an nvidia geforce 220 0r 240 GT or 9400 GT, my mother board has only pci express but these cards specify pci-express 2.0. I know they will work with my connection but will there performance be reduced by connecting via pci-express instead of pcie 2.0. If the performance is reduced i might aswell buy the cheapest?

A PCI Express 2.0 lane, IIRC, simply has double the bandwith of a PCI Express 1.1 lane. I doubt that either a GeForce 9400GT, GT 220 or GT 240 would use the bandwith of a PCI-e 1.1 16x lane, so, you would not find any performance loss - with those cards. I suggest you get a GeForce 9600GT instead of either of those cards.
An HD5870, a very fast card, runs identically at x8 mode in a x16 PCIe version 2 slot. So you could theoretically use up to an HD5870, however you couldn't purchase a fast enough CPU for a board that has no PCIe v2 slots.
In fact, most graphics cards would soon be CPU-limited in such a system. For example, an HD4770 is a little more than an X2-4800+ AMD CPU can support and your CPU would be lucky to have a third of the processing power as that CPU.

ummm I dont think he has mentioned his cpu yet....
i have a similar question.
is my ga-g41m-es2l (micro mobo from gigabyte) pcie 2.0? if it isn't will i lose any performance with an 5850?
