With your build you should have no problem with a gtx 960, just dont get two and SLI them, your power supply wattage is only high enough for one card long term
How do you know if the 750W is a good Gold quality PSU or not? He could easily run 2 960s on a 750 watter.
Agreed, GTX 960 is best. I suggest the 4GB models.
