The Radeon will beat the MX in just about everything. The Radeon has DDR memory where as the MX has SDR. The radeon has HArdware decoding right on the card, the MX does not. The Radeon has excellent 2D, the MX's 2D looks like crap. The only thing the MX has over the Radeon is better drivers, especially in W2k. I hear Linux drivers are also better with Nvidia. You probably should get the Radeon LE from
newegg. They have the Radeon LE for $77 shipped. If you're wondering what the LE version is, it's basically the same card, just has a certian feature called HyperZ disabled. You could enable it with a registry hack that a ton of people on here can tell you how to do. It's also clocked a bit slower and has a big heatsink instead of a smaller heatsinkwith a fan on it. You can easily over clock it to the speed of the regular radeon.
