how much would the gf4mx cost? My suggestion would be to go on ebay or pricewatch or something and pick up a Radeon 8500 if she needs good gaming performance. They're less than $100 now, and my 64mb non-LE ocs to 295 RAM/320 core and @ that speed, does 11-12k in 3dmark2001se on an ASUS A7N8X w/1GB DDR400 & a 2200+ @ 2600+ speeds... however, to get it to that core speed, I glued a 1u copper heatsink onto it, complete with 60mm low profile fan... I may unglue it and sandwich a pelt in there in the next few weeks tho...
As for the gf4mx, I've heard they overclock well... what would she be using the comp. for? The systems I've recommended for my Grandfather to use in his office (word, internet, some autocad stuff) use GF2MX400 64mb cards and do just fine... so do all the systems we just donated to Habitat For Humanity. Most of the office systems still run Diamond Viper 550s, and they're plenty fast enough for office & windows...
