Nearly 1000+ better? I mean I've got a dual core. In game performance is quite abit better on the GT's I know but I did not think benchmarks would be so big that I was getting a higher score than an overclocked gts and a quad core at almost the same speed.
GT's make an even bigger difference in benchies. unless you start putting quality in 3dmark06 up and adding AA.
the GTX's and Ultra's get lower scores than GT's and new GTS's at default 3dmark06 settings.
