I have been trying to decide whether I should get the MSI GTX 680 Lightning 2gb or the MSI GTX 680 Twin Frozr III 4gb. They are both the same price ($600) but I'm not sure if 4gb will really do me any justice. I plan on doing some minor overclocking for now and maybe a 3-4 years down the road, I plan on doing some heavier overclocking to match the cards that will be out by then. As of now my resolution is 1920 x 1080. I don't play skyrim and I don't think I ever will.
