AMD 7850 and 7870 question

[Nattefrost]

Hello guys, i want to buy one of those cards (7850 or 7870, depends on the starting price) and i have a following question.

I see they provide PCI-E 3.0 bandwidth, my motherboard its a cheap one @ 50$ ( Asus P8H61-MLX ) and CPU i5-2400. Since motherboard is PCI-E 2.0 i will benefit of all the power that HD7000 will provide?

Or my motherboard doesn't let me.

Thanks!

The 7850 and 7870 are priced at roughly 250 and 350 respectively.

The 7000 series cards are indeed compatible with pci-e 2.0 and it wont affect performance what so ever. There has been a few tests conducted with the 7970 gpu and at one stage a pci-e 2.0 scored higher benchmarks than pci-e 3.0 in some games by 1 or 2 points. The pci-e ports dont make a difference

Pci-e 3.0 doesn't give any advantage over PCI-e 2.0 for graphics devices, there will be no difference using a hd7000 in a 3.0 or a 2.0.

Theorically using the IVY bridge cpu you will get some performance (not tested yet).

But if you are going for a i5 sandy bridge there is no advantage going for a motherboard only for the 3.0.
