Hi, I'm attempting to select a single graphics card for a mini-itx build. Right now the Radeon 280x and the GTX 760 are the cards I'm most interested in. The radeon has a much lower price for a better preformance than the 760, but I know that Geforce Cards offer better Physx in games. this is a feature I want for games like Borderlands 2. My question is, will physx even be used in future games? Is it processor based anyways? Does it even matter anymore whether I got a 280 or a 760 for Physx use? What is the state of this engine and should I bother putting out more money for it in hopes of finding newer games that still use it.
