I have an e5400 clocked at 3.5 ghz on a Biostar g31-m7 TE motherboard and I'm looking to purchase a new graphics card to replace my 7600GT. The only problem is that my motherboard supports only PCIE 1 and not PCIE 2.
According to the motherboard manual, the pcie slot on this motherboard is pcie_1.0a compliant, maxed theoretical bandwidth of 4gb simultaneously per direction, for an aggregate of 8gb/s totally and supports a raw bit rate of 2.5gb/s on the data pin.
Most moderate graphics cards seem to be pcie 2 these days. I know that they are backwards compatible but doesn't that come at the cost of reduced performance? And if so, how much of a reduction are we talking about here?
I was thinking of getting either the 4830 or the 4770 but if my pcie 1 is going to cripple the performance noticeably, I may just opt to get a new mobo/build.
My aim is to be able to play Far Cry 2, SC2, Diablo 3? on very high/max @ 1400x900.
