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?
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
