Hello. I've been reading this forum for over a year, and now I would like to participate. I would like to upgrade the video card in my computer to something that will give me better performance. Does anyone have any suggestions on what I should buy. What is the best video card currently available for my machine. Someone told me that there are some ATI cards that won't work in my computer. So I wanted to be sure before I bought one. Thanks for any help you may be able to offer.
