I've used both ATI and Nvidia, myself. I had absolutely no problems at all with the MX400. I recommended the MX just because he said something about wanting a GF2. Either the Radeon or the GF2 would make a fine upgrade. Funneyperson and RainmaQer have it, though: if your friend can afford a $75 card, the 7500 is definately the way to go.
