I'm a little confused here. When the 8500 came out, i thought they reviewed it VS the GF3 and the nVidia came up slightly better in 3D stuff and the ATi cam up slightly better in the 2D stuff. Now people also say that the GF4 ti is a BIG step up faster, yet they still say its only slightly better than the 8500. I have a GF2 and an ATi7000 in my mac right now, and I'm kinda thinking about upgrading the GF2 to a GF4. Are there any good comprehensive unbiased reviews out there. The one down side of apple's move to nvidia, its very confusing, with they way their work.
