We can't really give you a set number, every GPU is different, just like a CPU. One person will be able to get 5.0ghz on one SB chip with the same cooling and setup, while one person may only be able to get 4.6 with one chip and the same setup. One person might be able to obtain 850/1200 on one GPU, but the other person can only reach 820/1150.
You have to fool around. Increase your core clock and run Kombustor until your display driver crashes/you see artifacts. Once you find your core clock you move onto memory clock.
Memory clock is a lot more tedious to find than the core clock because memory clock requires you to run lots of benchmarks and video games. Basically you do your normal stuff while testing different memory clocks. Once you start crashing, lower it down until you stop.
