3.0 PCIe on 2.0 Board?

[raven007]

m busy building pc for my cousin and got stuck here. my main question is.- will a 3.0 PCIe graphics card be compatible with a 2.0 PCIe motherboard?..If so, will there be any difference between using both 3.0 and 3.0 & 2.0 ?? will there be any changes to b made?

THANK U..

yes it will. GPUs are backwards compatible. I myself run a 3.0 GPU on a 3.0 mobo. However, since my CPU is 2.0 (2500k) I can not utilize 3.0 in gaming. but that's not an issue since games haven't really utilized 3.0 yet. 3.0 is like new technology in the future.

So if you have a 2.0 mobo and a 3.0 GPU you aren't bottlenecking your system. It'll work the same as if the mobo was 3.0.

Yes, it will work fine. PCIe2.0 is fine for most GPUs currently.

yep. it will work fine on pci-e 2.0. right now pci-e 3.0 is a marketing gimmick. there isn't a gpu in existence that can maximize a pci-e 2.0 x16 connection, and only a very few that can even max out a pci-e 2.0 x8 one (a 690/7990 will lose 8% of it's max performance in a pcie 2.0 x8 slot. a titan, 780, 770 and overclocked 7970 will all lose a little speed in one as well, otherwise no other gpu will even max out the pci-e 2.0 x8 port, let alone a x16 one).

we're still a few gpu generations away from pci-e 3.0 being needed for... anything.

yes it will definitely work. I am using HD 7950 which is a 3.0 PCIE and my mobo is ASUS M5A99FX pro r2.0 which has a pcie 2.0 slot. thanks.
