I picked up a compaq sr1830nx for a C note yesterday. Can ya'll suggest a video card? I don't "game". I do watch hd videos online (flash, wmv, mpg, etc.) and I will use the computer to watch standard dvd's on a 32" lcd with native 1360x768 rez via vga. I'd like to spend under $50, but that is flexible. Would ati be best since my cpu is amd?
