Hi there, I was just wondering if I could run 2x GTX 590s on my MSI Big Bang Marshal. I currently have 1 GTX 580 but I would like some more power for gaming in 3D etc. I know that my motherboard doesn't support Quad SLI but does that mean 4 GPUs or a Quad SLI Bridge. I can run SLI but I'm not sure that I can run 2 590s in SLI or does that count as Quad SLI. Also would my Corsair HX1050 new version be able to power the two cards.
