There's a review on TomsHardware with the 9500, 9500Pro, 9700, 9700Pro.
The only difference between a 9700 and 9500Pro is that the 9700 has 2x's the number of interconnects for memory, meaning 256bit vs 128bit. Other than that, it's the same exact card. Unless you're playing games on it, there will be no difference in PQ. Only speed in game playing on the PC.
