I figured as much. I wish I had gone with the 4 GB version instead. On that topic, would it be possible, and sensible, to sli my 2 GB with a 4 GB?
And with just the 2x 2GB 670's, if I'm not looking for super ultra max settings, and more like medium-ish, think it'd be possible to pull off 50-60+ frames in games such as BF3, Skyrim, Far Car 3?
You should have no problem getting those FPS, just turn AA and such down and overclock the cards as much as you can.
