I recently upgraded from a 775 build (q9550) to an 1155 build (3570k) and have enjoyed a huge jump in fps on Guild Wars 2. Most of this I attribute to going from PCIe 1.0 to 3.0. My 5870 runs at PCIe 2.0 and I am now wondering what kind of jump I would see if I upgraded to a PCIe3.0 card. From what I can see at hwcompare.com and on other various bench marks I don't really see a card out there that has huge gains from the 5870. Has anyone recently upgraded their 5870 on a 1155 platform and seen a huge FPS jump? If so, what card did you get? Ohh, btw I am still gaming at 1680x1050.
