hey guys i have a question on a EVGA X58 3xsli or E758 the way a put my loop my res cover the first 2 PCIE so i have to use the 3rd one , those that one have 16 lines? or is only x8?
16x (middle) if only the top 2 are used, if all 3 are used it's 8X's.
You'll be fine running 8x's with the 285. You won't notice a performance difference over 16x.
