What is the best way to overclock Kepler with GPUs?

I don't think there is a "best" way to do it.

What i do is:
1. Get the best configuration possible using cuda miner
2. Set memory clock to the lowest possible point (Mine is -502).
3. Increase the GPU clock by 10.
4. Wait 15 mins to see if you have any errors
5. If no errors or driver crashes go to step 3 else go to step 6.
6. If there are driver crashes or errors reduce gpu clock by 10
7. Profit!

Thanks for the tips!

actually, setting the memory clock at -512 decreases the hashrate and it is better to keep to its nominal value.
I noticed that some times ago while experimenting on scrypt. On scrypt you might loose something like 30~50 hash/s.

Depends on what you're mining...keccak uses barely any memory, so it doesn't matter.

Microcenter started selling GTX 750 and 750ti's, Msi twin forzr's in particular. I'm really tempted to get 4 of em.

I am thinking hard about getting 2 of the 750ti's to replace my gtx670. Well I am hoping that one card will be about as good as the 670 in performance. Don't want a major down grade from one card.
