Well,I decided to go with the MX200 because it was actually $39 at CompUSA. I couldn't get it to install however, apparently because it needs a Pentium II and I hava a Pentium I. So really my only choice is the TnT Riva 2. $69 is more than I wanted to spend but I was really looking forward to the improved framerates.
Oh well, it's only money right
