Would having gtx 670 and gtx 750 ti benefit or gtx 670 alone?

Solution
You could use one of them as a dedicated PhysX GPU if your MB supports this although I wouldn't really reccomend it since all your really doing is using more power/generating more heat just for a small increase in performance on games that utilize PhysX. Personally ive seen increases from 2-8 FPS but its not really worth it, your better off just selling the GTX 750 ti.
