You can get 2 - 2.1Mh easy with your 750ti.
My ccminer:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
ccminer50.exe --algo=x11 -o stratum+tcp://eu.wafflepool.com:3331 -u xxxx -p d=0.008
Overclock setting:

So even with this happy little gpu, the temps tend to go really high really fast. I'll probably try with a different setup with risers later, but for now this has to do.
But I'm still curious why the difference in MHash between pools.
