Yes,the 750 can run with your rig,I don't see the 4gb gt 640 and that card don't have anything to do with upgrading to a 750.

The 750 only uses power from the pci e x16 slot,so no point getting a new PSU,and its tdp is about 55w tdp (what i see in tomshardware review)
the pci e x16 provides 75w max so,its a YES!
