I'm just curious about this. I'm pretty sure the answer is no and I only found one semi-relevant article about this HERE. And even that article doesn't really state anything other than "not now" pretty much. I'm curious because I have a GTS450 I got back from doing an RMA recently (overkill I know for Physx), and I plan on getting a mid-range 7xxx series card soon. So, if it's supported, how easy is it to set up? If it's not supported, then how much work is it to "hack" the OS/drivers to make it work? That is, if it's worth it.
