I currently have an Asus p8z68 v-lx with i5 2400 CPU overclocked to 3.6Ghz, 8GB RAM and 1 already installed Sapphire HD6870 GPU. So the issue is that the 2nd PCIe lane bandwidth is x4 which I do found some were saying that the performance difference is not really noticeable. Is this through? Has anyone here is having the same dilemma as I am or perhaps maybe had gone through it? Appreciate a comment
Will the degrade be below 5% out of the expected performance on 2 x16 PCIEs?
