Alright so on my now build i was thinking of getting the following motherboard: GIGABYTE GA-Z68A-D3H-B3.

How ever this motherboard does not support PCIe 3.0, and i was thinking of getting the following graphics card: XFX Double D FX-795A-TDFC Radeon HD 7950

So what do you guys think, will that card work on a PCIe2.0? or should i change the graphics card for a EVGA 03G-P3-1584-AR GeForce GTX 580 ?


The links for the components mentioned above are the following:

Yes it will work just fine on a PCI-E 2.0 slot.
Current cards can't even saturate x8 lanes.(4GT/s).
The difference between 3.0 and 2.0 is like 1%.currently.

Something that will be improved down the road no doubt in future platforms.
Can you say e-peen.

Dude! i'm biased when it comes to video cards.
Radeon only for 10+yrs.
Both cards are very good(equals in alot of games) but Amd is so much better for power consumption and price/performance.(in that comparison anyways, the 7950 is the winner).
I hate gpu comparisons btw, cuz i'm sure the GTX680(when available) will probably spank the 7950.
But once again price/performance will equal that out.
