3.0 pcie in a 2.0 only supported motherboard?

[Justin Dzubinski]

Hi there,

I really have my little heart set on buying a 8 core amd processor, with a compatible motherboard that only supports 2.0 pciE. Ive seen 3.0 doesnt seem to make a huge difference, but still, it has 4 gb of video ram on it and I love this idea.

MY question is, what would happen if i stuck this 3.0 pcie in my 2.0 only supported motherboard? would it even work? would the 4gb of video memory be ultilized for even the most intense games?

the links for my parts im gonna buy is :

motherboard: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3184372&CatId=7246

and the imfamous video card: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8466655&CatId=7387

I ALSO LOVE THE IDEA OF 4GB on a video and AND DDR5 but its hard to find one thats not 1000 dollars lol

Any thoughts fellas?

Video cards are downward compatible. So a PCIE 3.0 video card will work in a 2.0 slot.

That video card won't even fully saturate (fully "use") the PCIE 2.0 bandwidth, so no performance drops from "bottlenecking"
