PCI-E 3.0 Graphics cards on PCI-E 2.0 mobo

[Firzenizer]

I was just looking at new nvidia Kepler cards and I was wondering if there will be any problems running those new 6xx-series cards on PCI-E 2.0 as they are made for 3.0. I have read some articles and stuff and I am pretty confident that there is no problem but just wanted a confirmation

As far as I know those cards wont exceed the 16GB/s bandwidth maximum that is maximum for 2.0 afaik. But would there be any other problems?

and the mobo I have is Asus P8P67 Deluxe

Running a 7970 on pci-e 2.0 without a hitch.

Anyone ?

You do realize that the 7970 is pci-e 3.0 as well right? Yes itll work.

I already know, that it works, but the question was will there be any problems with it such as memory bandwidth is not enough or something.

I do know that I can put 5 horse power motor on a car but the car won't go very fast.

I believe that a pci-e 3.0 card will not saturate the bus completely. There have been tests that have been discussed here on this board. I cant recall them exactly but the general jist is that 3.0 isnt much different than 2.0 right now.

the pcie 3.0 will work fine on 2.0board

here is the benchmarking and benefits of the pcie 3.0

I do believe that you will not get true PCI 3.0 performance until the Ivy Bridge cpu comes out anyway which will then be 32x instead of 16x.
