Question about haveing a dedicated physx card

[Honfold]

So I replaced my gtx 660 with two 770s factory OC in sli. however i still have my 660 and my question is should i use it as a dedicated physx card? i have a 1200 watt power supply. thank for any answers.

It depends on the games you are playing. The GTX770's would realistically be able to handle the Physx better by themselves than with the 660.
