For that level of system, either would do fine. If budget is king, then they will do.
For your system though you don't need 650w or 750. A good branded 550w like this would do perfectly:

This will be a really good buy, and will power your system with room to spare and you get a 10 year warranty.
It's a great PSU, and is worth the extra 20$ you might pay for it over one of those ones you've mentioned.
