Kinda, but it's much better to use 1.

Why do you want to do this?

they don't share the same digi ground so not sure if the MOBO/ GPU will like it. I'd stick to one solid supply

But, really for what reason do you want 2 PSU's? It will adversely effect efficiency, performance etc, and would be much better to stick with one.

But the HX750 should be enough to power a system with a Core2Duo and three 9800 GTX+'s.

Honestly, the only time you would need 2 PSUs is when you're running 4 580s and 2 5680s (2 1000watt+ PSU), not something 1 PSU can do easily.
