The guys at the Inq have laid out the tables of numbers for the upcoming mid-range offerings from nVidia. They're only 3DMark numbers, but teh 8800GTS 320MB gets a 9429 in 3DMark06 at 1280X1024 for comparison.

"It looks like a decent spread, the 8500 is pretty weak, but it is the low end card. The 8600 twins are right on top of each other, if there is anything more than a few dollars separating them, the 8600GT will be the bargain of the bunch."
