That's what I did as well. I run the 2-28 version for my 650 Ti BOOST and the newer version for my 750 Ti. Did see a slight (less than 1%) bump in khs on Scrypt with the new version using the same clock settings. I'm still closing in on the 300khs speed, up to 297khs running stable at 65C now.
So what settings are you using for your 750ti? I am running the EVGA 02G-P4-3753-KR. My miner seems to crash all the time and I have just now figured out a more stable situation...and as I typed that it crashed after about 9 hours of running. my miner does this for not sure how long (image below) and continues to mine with the remaining cards that didn't crash until the PC completely crashed and I powercycle it manually.

this. Will paste them in when I get home and turn my computer back on. And now that I see the new CudaMiner is available (Why is it not on the 1st post in this forum) I will download and check what results I am getting and see if they keep crashing.
