Good physX card for two 560tis

[lt_dan_zsu]

What would be a good physX card be for 2 560ti's. If I were to do this I would want to do it for a pretty low price. Also there is the factor that I am using a 700w power supply. So I am using most of that with my current system. So what would be a good option for a physX card that uses low power?

if you could get a hold of a 9600gt that would work perfect or a gt240 would be comparable

considering most games dont really chug on the physx end, you dont need a tremendous amount of physx power, both these cards are under 100w tdp and would work great

full system specs?

2 560tis should be plenty of physX power...
