I have an older system, a Dell Optiplex 8400, though I have upgraded a fair amount over the years. It currently is running Windows XP with a P4 3.4GHz, 3 GB of RAM, and a Radeon x1800 for my video card. The power supply is either 400 or 450W, and I shouldn't need a low profile card. I'm hoping to run new games like Dragon Age at fairly low resolutions (1280x1024 ideally, though 800x600 is more likely). I was hoping for suggestions for a replacement video card. My budget is in the $50-$100 range, though I don't want to buy something that way overshoots the rest of my system. I've been eying a Radeon 4670, though I am not sure that is really the best fit. Thanks.
