So, I noticed my new motherboards only has PCI-e 2.0. But my GPU is PCI-e 3.0. Does this mean my GPU isn't compatible with this motherboard? Or will my GPU just run slower. That's what I've been hearing lately. Just need to be sure. Thanks.
 
Solution
On extreme high end graphics cards there is a SMALL, extremely small difference in performance.

But its minimal.

Perfectly compatible.

i don't think theres a card on the market that uses all the theoretical bandwidth of PCIE 2.0. that being said 3.0 has been tested to yield a few frames more with some cards 1-7 (or something like that)
 


And those differences are only observable in highly synthetic benchmarks, gaming isnt affected at all (or within margin of error type of difference).

As long as your plugging into a PCIe Gen2 8x slot or better, your good.

Thanks. My MoBo is an MSI FM2-A75MA-E35 FM2 Socket and my GPU is a Sapphire Radeon HD 7850.
 


Precisely. :)
