I am putting together a new build and I am stumped on what graphics card to get. I have around a $400.00 budget and I would like to stick with EVGA since I have good luck with them for so long. I cannot decide on if I should get two 560's or a single 570/580, or if those cards should be 2560mb. I play Skyrim with plenty of mods, BF3, Flight Sims etc.
