I've had my computer for about 4 years and it came with a mid to low end video card (at the time). It's a Nvidia GeForce2 MX400. I was wondering which card I can get that would maximize the performance of my system. Here are my specs: P4 1.8GHz 768MB RAM (one 512, two 128) AGP 4x 2.0 I know the CPU can be a bottleneck, so which card would be optimal for that setup? Thanks.
