I'm not sure if this is the correct place to post this but if it is GREAT!! I have one question and that is I built a pentium 4 2.8 computer a year ago and I installed a ati x1600 video card. the computer shows that I have 664mb ram. A week ago i purchased a game called Heroes 5, Tribes of the East and also Titan Quest. When I try to play them, I can play but the screen is really jerky and it sucks to play either of those games. My question is is my processor to old, do I need a different video card or do I need more memory.
