I recently finished my build based around the Gigabyte G1 Sniper B7 motherboard, and I am quite happy with the performance. I am running an HD 7950, and I was wondering if my motherboard would support crossfire. The board itself says "Crossfire Technology" but only has one x16 slot, and one x4 slot. I have heard that people who run dual graphics cards in the different slots find the performance increase to be negligible, or even hindered. Thanks, Aidan
