Any good guess how many NDI sources could i7 4770K + 750Ti handle properly ?

Not a fan of guessing, but I have tried an experiment. I used NDI Tools and the Sienna test signal app to create 4 NDI sources. That's the limit of the utility computers I could draw into service.

My vMix system handled 4 - 1080p sources without issue. CPU around 15%

It's i7-5775C quad-core
16 GB Memory
GTX 750 Ti

Incidentally, I wish that the Newtek Test pattern generator has the ability to play a looping animation at a specified frame rate. The Sienna Test Signal Generator (OSX) does this. It's very handy to play a countdown leader known to be at 60p

NDI Sources are about a 5% hit per Source to CPU resources depending on the Source and your CPU.
The 4770K could probably handle 5 or 6 without issue as long as you don't have a lot of other demands on the CPU.
As always, you are best to test for yourself just how far you can push your system before you start having issues.
