I am experiencing slowdown and framerate drops in some new graphically intensive games. I have an ATI Radeon 9000 Pro 128 MB DDR. When the slowdown occurs, my processor isn't really buzzing with much activity which leads me to believe the slowdown is in the video card. This leads me to believe that I should upgrade. Do you all agree?
Intel P4 2.4 ghrtz w/hyperthreading
1024MB DDR RAM
Win XP Home
P.S. The games are the PC version of Halo and Rainbow Six 3: Raven Shield (Great game by the way)
