I bought Battlefront II - but the video card that I have sucks. I need to know which one would be best for my PC. Unfortunately I'm limited to only a PCI card. I'm looking at the ATI Radeon 9250 256mb for $99.99 or the Nvidia card FX5500. Which do you think would give the best preformance? I have a Pent 4 - with 512mb mem.
