Hey guys, Well before you throw me under the bus, I have a noob question, and its not about an Apple product. A co-worker of mine has me upgrading his kid's computer over the holiday break. It is a Dell Dimension 2300. Now I realize this is a Mac forum, and I own all Macs, but I need some help. Question is, how do you know what type of video card will run in a computer. There is so many choices out there, and i'd hate to buy a video card that wont run in the pc. I've upgraded everything else (burner/ram/card reader/sound card)for him so far, but i cant seem to find a good guide on what I should be looking for as far as video cards. Any suggestions?
