That is funny, I have the same card and asking myself the same question...
I was expecting 7950 to sell for cheap after the ASICs hit the bitcoin mining, but I did not see that much movement tbh. Where I live, the NVidia 700 series launch did not even make a dent in the 7950 pricing, and now with the R-series coming out the prices finally dropped 20%, but are already showing signs of bouncing up to what they were prior to AMD's announcement. The "smart" thing would be to buy right now while there is still stock and cross fire. But I already have ~80 fps @ 1080p in my most played game (MechWarrior), so I do not think going cross fire is so smart after all...
What I heard rumoured is that one can save the game codes for later, and BF4 is supposed to be added to the Never Settle Bundle in Dec. If that holds true, it might be a game changer for me.
