I did a comparsison a while back and showed the results. Basically the MX sux more than the Radeon. The Radeon actually matches the GTS in 3D Mark 2001. The best Radeon deal is the LE, which goes for less than $70. Not to be confused with the VE, the LE comes with the full version chip and 32MB of DDR memory. It is avialable only as an OEM card.
