AMD 7870 or Nvidia 660 (non-ti)

[xbread]

Hey guys! I'm a bit stuck on this decision right now. I'm in the market for a new gpu (upgrading from a 9800 GT).

My specs are as follows:
M5A87 Mobo
AMD Phenom II x4 970 3.5Ghz
8GB Corsair XMS3 1600Mhz
Corsair CX600 PSU
Thermaltake V4 Black Edition

I currently play Battlefield 3, Skyrim, some indie games, Borderlands 2, Civ V, and the Witcher 2. I'm also planning on playing Battlefield 4, Watch Dogs, etc. in the future.
Aside from gaming, I do graphic design work on Illustrator + Photoshop CS6, and light video editing on Vegas.

The EVGA 660 is currently running for around $190, + with the VALPAK10 coupon, ends up being $193 w/ tax (before rebates).

The Sapphire 7870 Ghz Edition is $240 (w/ tax is almost $260 before rebates)

But they include Bioshock Infinite and Tomb Raider for free.

So which one is a better deal? Should I wait for the 7870 to drop in price?

i haven't seen direct comparisons between the two. but my vote has to go with 7870, wider bus mainly.
if this was a 660Ti vs 7870 then probably ill go with the green guys.
