Look at what the 9600XT benches at, you'll be right around there, probably plus a little more with the 9500pro.
The 9600XT is very near the performance of the 9500 Pro, the 9600 XT is about 10% slower in the core (pipelines x MHz) and about 10% faster in the memory. So on games that rely on core speed more than memory the 9500 pro will have a slight advantage and in games that rely more on memory bandwidth, the 9600xt will have the advantage. In every case, they perform pretty close to one another, so you can use that as a decent reference if you can't find benchmarks with your specific card.
