Quick question- I'm currently using an 8800GT and a Core 2 Duo E6750. The combo's fine for my 22" monitor at 1680x1050 with just about every game bar Crysis, but I'd like to get a new 24" or 26" monitor. If I was to upgrade to an ATI HD 5850, would I get the full benefit from it, or would my cpu hold it back?
