I'm looking to buy another HD 7850 and create a crossfire setup. However, to do this, I am having to buy a new motherboard that has two pcie expansion slots. I've noticed that the cheaper 970 range boards have one 16x slot and one 8x slot, compared to the more expensive 990X range boards that have two 16x slots.
I would like to save some money and go with the cheaper board, but is it possible to run two cards with one in the 16x slot and the other in the 8x slot without any sort of noticeable performance decrease?
