I've heard that you can have two graphics cards from nvidia and one could be like a gtx 560ti and the other could be a gt 520 and you can setup your computer to use the gt 520 to run all the phyX stuff and the gtx 560ti to run everything else? how do you do this ? is it possible ?
A GT520 isn't really powerful enough to make physx run smoothly but it's performance is far superior than any cpu in physx. I suggest at least a GT430 or a GT240 while almost any G92 based card is best for dedicated physx.
