ATI Radeon 9000 pro or Radeon 9100 AKA 8500

Hi, Im finally going to upgrade my Geforce 2 mx to either a Radeon 9000 pro or a Radeon 9100 (AKA the 8500 brought back with just a new name no other improvements but still looks like a very good deal at under $100). I was wondering which one should I get since both look very good on paper and in reviews. I do plan to use fs2002 exclusively on this PC and FSCOF when it comes out. The reason Im Jumping off the nvidia waon is it seems like you get more for your money with the 9000 pro and 9100 radeon cards. for $70 you get a Directx 8.0 card with vertex shaders and everything. On Nvidias side $70 gets you a Directx 7.0 card. Which one should I get? The 9000pro is newer and has more features but a bit slower than the older Radeon 8500 chip on Benchmarks. So now Im stuck deciding to go with either a slower chip but more features or go with the faster 8500 AKA 9100?Andrew
