GTX680 with GTX560 SLi

[thespeedding]

Hello, now I'm running GTX560 SLi... I want to buy GTX680... Can I run GTX560 SLi as PhysX dedicated cards ? Is it possible ? Which PSU will I need ? Can run one GTX560 in x4 and second in 16x with SLi bridge?
I have: ASUS P8P67 Evo, Intel core i7 @ 3,4GHz... Thanks

You could run one of the GTX 560 as PhysX card, but it's not worth it.
