A lot of people do not understand in here that 7680x1440 is a monsterous gaming resolution, your going to need all the bandwidth you can get. Your best option is to Crossfire 7970Ghz, and when you make the move to Sandy Bridge E grab a 3rd 7970Ghz. Grab a 1200watt power supply like a Corsair, Kingwin, Antec, Cougar, PC, Coolmaster Silent Pro! I would not worry about AMD or Nvidia refresh cycles they are far away and its more than likely a pair of 7970 can handle anything for the next two years even more for TriFire
