Agreed. *ANY* Radeon (with the exception of the VE) will beat an MX card, even when using SDRAM. (Do MX owners need a reminding that their cards are using SDRAM as well?)
A 7200 SDR may not be running circles around it, but it'll almost certainly be the same speed or faster. Most times a fair bit faster.
And guaranteed awesome 2D quality, something nVidia cards still lack (luck of the draw.)
