Don't worry, you don't need a PCIE 3.0 motherboard, as the 3.0 cards are backwards compatible with PCIE 2.0. Also there is no difference in performance when running a PCIE 3.0 card in a PCIE 2.0 motherboard. The only time you will see a difference with PCIE 2.0 is if you run two or more cards in SLI, and even then the difference is marginal. So don't worry about that. Well the 480 for $210 is a nice deal, as it performs like a more expensive gtx570. However if you can wait that would open up more possibilities, as Nvidia should release more cards soon.
