I'm looking to get a new graphics card for my G4 AGP 450Mhz machine and I'm wondering if anyone knows which graphics card is better, the ATI 8500 or the ATI 9000. The ATI 8500 still cost about $200 before tax but I saw the ATI 9000 for $150. I was wondering why would ATI make the new card cheaper than the older card. Is the older ATI 8500 still better and that's why it cost more? Any ideas or suggestions would be great!!!
