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

post #1 of 16
Thread Starter 
I plan on upgrading my GPU. Will the 2.0 card work just as fast in a PCI
express *16 slot?

It will work but not as fast you will get the PCI-e x16 speed but not the double bandwidth of the PCI-e 2.0. The PCI-e 2.0 is backwards compatible tho so yea it wil still work

Yes, it will work fine, though it will not be running at 2.0 speed. It will only will run at the older version speed because your motherboard does not support the new version speed.

correct me if im wrong but i dont think you will notice any difference running a pcie 2.0 card on a pcie 1.0 slot as graphics cards dont even use the full potential bandwidth of the pcie 1.0.... im sure ive read that somewhere ??

It all depends on your graphix card too. My 8800GT is a PCI-E 2.0 card so yea it does use the full potential of the 2.0 interface but a regular PCI-E x16 card will just use the standard speed

PCI-E 2.0 is just a gimmick. I lost no graphics performance when I went from my Maximus Formula to my DFI DK P35.

so if i got a new MB that has a PCIE 2.0 slot i would get more performance/FPS in games and benchies than i get now because im using a PCIE 1.0 slot ???

Theoretically yes but the gain isnt that noticeable its more for people(like myself) who feel safe in the knowledge that they have the newest thing out...Lol!. But yea i mean I really dont think the bandwidth would reach its limit so dont go and redo your whole system because of the 2.0 interface but if you have the 2.0 slots and are in the market for a new video card then yea why not get a 2.0 card
