well, if your inclined to have less problems with running TSL, i'd recommend that you go with a nvidia geforce fx5200. its about the same price and performance, and you won't run into a lot of driver issues with it like you will with a radeon (of any kind).
however, if your set on getting a radeon, the 9200 will work just fine, except for the driver issues.
