I have an ATI Radeon 8500. Just upgraded CPU to P4 - 2.7, 768 DDR RAM, Asus P4b533 MB. Considering upgrading the graphics card. Would I see a "significant" increase in performance (use computer for photo editing and playing games) by going to a 9700 Pro? Is it worth the cost? Should I wait until the next gen of ATI cards and either get one of those or wait for the 9700 to drop when those come out? Thanks for any advice.
