Considering doing dual GTX 280 on a 24" monitor or simply just one. With cost not a factor (so no use posting not worth it from price standpoint or I'd be better with something else at this price), is it worth it at this resolution fron quality and speed standpoint? Will I see enough improvement? This is definately my card of choice regardless of price, but hate to waste power and add heat when I may not see big returns at this resolution. Thanks for your help as purchasing a new computer this week. CPU - QX9770 Motherboard - EVGA 790i RAM - 4g Also depending on one or two GTX 280's, what is recommend power supply? Again thanks for feedback.
