the performance can be calculated as number of cores * core clock. i only have numbers for the 9600M-GT (20 chains/sec at 500mhz) and the GTX260 (140 chains/sec at 576 mhz). The 9600M-GT has 32 cores. So a 9600GT with 64 cores and a slightly higher clock should be able to do 42 chains/sec. (for example)
