what is better for gaming. I have 2 GTX 480 sli linked. Is it worth the extra money for 2 slots at x16. Looking upgrade CPU and Mobo. Thinking going with i5 or i7 sandy bridge, but at a lose with the PCIe 2.0 speed I want if the cost is justifies the two PCIe 2.0 at x16. If someone could point me in the right direction.
From what I've seen online in some testing x8/x8 is only roughly about 5% to 8% lower in terms of performance compared to x16/x16. So it really comes down to how much that amount of performance is worth to you and your budget, and could the extra cost of the higher end MoBo be better spent elsewhere. At least that's how I looked at it, and I wound up going with a x8/x8 MoBo.
