PCIe3 offers double the bandwidth per lane than PCIe2. In terms of gaming performance, makes no difference as long as your connecting to a PCIe2 8x slot or better. Its more of a future proofing thing for workstation grade cards and PCIe based storage.
You will see no difference in performance by any video cards yet out there between PCIe 2 and 3.
