I'm considering doing a quick and dirty upgrade from my overclocked 3800x2 at 2.7 to a e2160 at about 3.0. My concern is will the quicker speeds of the 2160 more than make up for it's smaller cache when gaming? I'd be using my 8800gts with it. Is this a worthy upgrade? I'd be going with the Gigabyte GA-P35-DS3L for a motherboard.
