Is http://www.cudaminers.net/ working for you , cause i can`t open it for 3 days now.

Its working for me aswell. Certain sites wont load for me either but will load through my phone

How do I know which compute version 750Ti's are? Thanks.

Compute 3.5

as nomad1109 linked, 750 and 750Ti's are actually compute 5.0

We simply run them under compute 3.5 normally in the miners

Thanks. Are you seeing noticeable differences between running sources vs 2-28 version?

of cudaminer ? I think there was some improvement for keccak and blake also ( Huh

I am kind of lost in all the update, I have so many version Grin
