PhysX is pretty much in it's infancy. There are only two full games out right now that utilize PhysX which runs on Nvidia GPU's. They are Mirrors Edge and Cryostasis.
There are other games that demonstrate GPU PhysX in only certain levels, such as GRAW2 and Unreal Tournament 3.
As far as developer support. Many big names devs like "EA" have signed over the past year and are currently developing games. A few more games "should" launch over the summer.
The games you had mentioned though, do not have GPU based PhysX. So, you wouldn't notice any difference using PhysX or not, because there is no difference.
The only thing that 8800GTS would do in the second PCI-e slot is eat up electricity. Unless of course you buy the two full titles I mentioned above. Then it would actually utilize the Nvidia GPU's to run PhysX because the games support it.
As far as PhysX becoming the "next big thing", well, you'll hear opinions from all over and of vastly differing perspectives, but IMHO, PhysX will be big, yes. It already has the momentum of tier one devs backing it.
