Nvidia owns the physx tech. AMD can not use it. Physx is nothing like SLI, and AMDs cross card CFx does not emulate it. Physx is responsible for emulating real world physics for objects in the game. If you use an AMD card, it off loads physics processing onto the processor.
You make things a lot more complicated than they need to be. AMD does not do physics period. AMD drivers offload physics on the processor, which is a less than optimal solution.
A GTX260 Physics on a GTX680 is crap anyway. It will be holding the 680 back. You need similar cards to get and serious advantage from Physics.
Yeah look at the benchmarks, sometimes you're only getting one or two FPS more by adding a 260, whilst sucking up a lot more power and creating a lot more heat!
PhysX is an NVIDIA technology. Doesn't happen on AMD cards.
I run some bench and look on results:
Mafia 2:
GTX680 alone - avg. 47,1
GTX680 + GTX260 - avg. 56,4
Batman AC:
GTX680 alone - avg. 47,2
GTX680 + GTX260 - avg. 52,6
Metro 2033:
GTX680 alone - avg. 29,2
GTX680 + GTX260 - avg. 31,0
Enjoy!

I don't believe it. You had to have PhysX set to the CPU instead of the 680 to get those results. What resolution are you gaming on anyway?
Is PhysX set to run on the 260 in the NVIDIA Control Panel though?
1920x1080, but remember i've got i5 on '56 socket and only 4,0 GHz
Does it, actually make a difference?
Lol, it's like SLI but with different cards and less performance boost .

Yeah OK? Thats certainly no bottleneck. There really isn't much different in gaming between Lynnfield and Sandy bridge. I went from an I5 750 at 4.2ghz to a 2500k at 4.6ghz and the only difference I saw was lower temps.
At 1080p, a 680 should dominate any game at any setting, even metro 2033, without the need to a descreet physX card. Still willing to bet that when you had just the 680 in you had PhysX set to CPU and not to the 680.
Lol that's funny as hell.Maybe I have 15 years old computer,but I think my environment is better anyway (first 2 pictures simply show where we all are...including me lol):
Of course I will not show you the computer room from which I operate all that data and I will also not give you an address where I live lol.
Cheers!
