I have a P3 550 mhz 256pc100 and a gladiac geforce 2 ultra. The original core clock was set at 250 and core memory was 458. I have set my memory to 468 and I really cant notice any signifacant difference yet running tribes 2 . I really would like to hear some other peoples experience with a similar situation. My main question is how much more should I try and push the memory and should I increase the core as well, or does it matter.
