Some of you might know that I bought an defective HD 4870 which would not output sound through standard HDMI adaptors. Well, I returned it and got a GTS 250 instead, and it is working perfectly. I wasn't really concerned with PhysX, since most of the talk here makes it sound like it doesn't do anything and is just a gimmick. However, yesterday I picked up Batman Arkham Asylum and I have to say I'm loving PhysX! All the little extra effects, as unneeded as they are, are really neat. The best part was that I didn't have to turn down any graphical settings to use it, the game is just as smooth with or without PhysX enabled on my GTS 250. I think once I beat Batman I'm going to go get Metro2033 and try that out. Now that I'm out of school for the summer and working full time, I'm definitely going to start saving for a GTX 465 or 470, I was hoping for an HD 5830 or HD5850, but after seeing what PhysX can do, I'm not even considering them. I wish PhysX worked in every game.
