So I just recently ordered my new sound card (Xonar ST) and realized with my two 580s, it simply won't fit if both cards use the first two PCI-E slots that are x8/x8 in SLI. So my only other option is to use the second card on the third PCI-E slot which is only capable of x4. I was just wondering if there will be any noticeable performance difference between two 580s at x8/x8 and two at x8/x4.
