Two 660tis will give you better performance than a single 680, but you could probably get good money for the 660ti. I would buy the 670 or 680 (which, in itself is an upgrade over a 660ti) and grab another 670 or 680 in the future by selling the 660ti you currently own. m 0 l Can't find your answer ? Ask !
