I'd say right now the choice is very difficult to make (unless you'd go for a GF4, of course). The GF3 and the 8500 are rather on a par. Of course, Radeon has several advantages (dual display etc.) and it looks more futureproof actually. It's also cheaper than the GF3 Ti500. And ATI's drivers HAVE matured finally. But nVidia should be a little more reliable. Tough choice...
