I'm thinking about getting a new video card. I am considering a GeForce 4 Ti4200, or maybe even a Ti4600. I want to run the games at 1024x768 with all graphical enhancements available, like 4x anti-aliasing, and keep a framerate of 60 or above. I'm wondering if my CPU might hold me back if I upgraded though. So, I'm not sure if I will. :-/
