hi i am not very knowledgeable in the world of videocards but i know the basics. I've been looking at performance charts for the GeForce 4 Ti series vs. ATI and it looks like a close race, but Nvidia looked like it was a bit better. I'm thinking of buying a ti4200, but i don't know what make is better. I have a pentium 3 1Ghz processor with 320mb of memory, 133mHz bus speed, and an asus tusl2 motherboard. i'm willing to spend $150 max, but i also want good quality and speed. it will be used mainly for gaming. Is there a difference between, for example, gainaward, leadtek, chaintech, asus, abit, msi, & powercolor for the ti4200? and is ati a better deal, for example the 8500 series?
