I got Dark Physics not long ago, but I don't have a PhysX enabled GPU and so fluids won't work at all, and most of the more demanding demos like "PhysX Island" or "PhysX Museum" have rather low frame rates (like, 10fps on a good day). So, I'm after a new and much better graphics card.
I'm thinking of an nVidia GeForce GTS 250. I was just wondering if anyone had used it, how good it had been, and if it
a) had a PhysX chip on it, and
b) if not, could it still handle all the features including fluids?
I've also considered the nVidia GeForce 9800GT, but I was told that is a little older and not as powerful as the GTS250. So, any comments or opinions would be much appreciated - I really want to be able to use the full power of Dark Physics, and especially the fluids!
[Edit] Just been reading around about fluids, and it seems there have been some trouble using them. Will upgrading to Windows Vista and DirectX 10 pose any problems with Dark Physics?
