ColdfireTrilogy :
you are telling him to NOT take into consideration Physx yet pressing the importance of GPU compute for gaming, what backwards thinking is that?? As little as physx is used, even by gamers due to its relatively low inclusion in games, I can almost guarantee the number of maintstream gamers readily using their GPUs as compute devices is fractional. To tell him to ignore physx and then say compute is even relevant (its not) for mainstream gaming ... okay 0_0.
I do not understand even a single thing from your message?

You don't have the 7870 and the 7850 option from the red team. You have a 7950 which is faster and a 7870XT, which is faster. I'm kinda leaning towards the 7870XT for being a $50 cheaper than the 660Ti/7950 and performs just a bit slower than those two cards, the only problem that it has is that it has 2GB memory and you lost game bundles. As for PhysX, you better set this problem aside for now, because it is not that important and you can get a Dedicated PPU with an AMD card (which possibly be a GT640 or something else).
So it all depends on you. All is good, pick the one you like
.
Oh yes, I have learned something new. It was the worst of its kind.
PS. You can take a look at a 670. Some of them are below $350 and it's great for the price compared to the other cards.
EDIT: (this was written before you made the choice)
Good choice. Yes it should be compatible. I would recommend you to buy cards from good brands. Have a Good Luck!
