I used to have a fx 4100 with a 650 and it worked fine. You will get better performance by spending more on the gpu instead of the cpu. The fx 6300 is a great match for any type of 650 card (ti, boost, etc...) If you can, I would see how much the 660 is. But between the 2 options I would go with the first option. Most games mainly rely on the gpu over the cpu
