9000Pro would be better.
The 9200 is a 9000 with 8x AGP (worthless).
The Pro will have higher clock speeds, so will be faster.
Neither card will be very good for gaming though, try finding a used Ti4200 or 9500Pro, they may be fairly cheap.
The only *real* decent gaming options are 5900XT and 9700/9800 (refurb for both cards, since you are on a budget).
