I was going to put one of my 280s in my new rig for PhysX, but on reflection, I'd rather not mess around with hacks etc for the extremely limited gains that PhysX affords.
I'd give up PhysX long before I'd give up AA for example. But as you said, it's entirely subjective. I saw a video of Mafia 2's PhysX and it looks weak IMHO. Then again, I wasn't holding out much hope that Mafia 2 would be even half as good as the 1st one , regardless of PhysX.
I agree with you to a point. It is true that games that use PhysX seem to add little as what the Dev adds is usually 1 huge effect or 2 big ones and that is all. But the difference here is as Rollo says, Atleast it is out there and Nvidia is pushing GPU based physics mean while we are all still waiting to for ATI to do something, anything, in any game that is GPU physics based.
