I currently own a GA-H97m-Gaming 3 motherboard, and I was seriously thinking about getting dual RX480 cards, as I have x16 and a x4 PCIe, back in the day of the 8000 GT's I had a pair of 8600 in SLI, with a GA-M57SLI-S4 and I never noticed any benefit from having 2 cards (in SLI enabled games). I don't really know if it was because of my poor cards or what, but I don't know how is it working nowadays with SLI-Xfire, so I would really appreaciate some input on this matter.
