I'm thinking of adding a second Nvidia card for physx. My current card is an EVGA GTX 660 2GB SC. What sub~$100 card will work or should I be looking at something in the 100-150 dollar range?

i5-3570k @4.5
2x8GB corsair vengeance 1600 9-9-9-24 ram
GTX 660 2GB SC
1000W OCZ 80% gold modular with single 12v rail rated at roughly 114A i think.

There's no card worth it, you could put in there a 650 or 650 ti for physX but it's not worth it, just get another one 660 gtx for SLI if you want to, it will be better.

Yeah but my motherboard doesn't support Sli. It is a ASROCK Z77 PRO3 with only crossfire support.

Do you play a TON of games with Physx? If you don't it's not worth it; trust me. You could probably buy a 550Ti and it would be just fine but it would be a power hog and almost pointless as Physx isn't going to slow that 660 down enough to make it worth buying a seperate card for.

Reason I'm looking at a dedicated card is that planetside 2 has physx option but it is disabled in the options. So I assumed I needed a second card set as a dedicated physx.

Hmmm... odd I never saw that option I'll have to check it out later. If you have an nVidia card it can run Physx. Having a dedicated card can increase the overall performance as the main GPU won't be doing the calculations through PhysX

I googled it and finally found that the option is grayed out for now because of issues with drivers. :(
