960 or 280 or 285

I'm in Canada and about to upgrade my GPU. My GF is getting into some gaming so I'm going to give her my 7870 and get something for me for $250

That is basically my selection.

I could squeeze out a 280x but it's "Club 3D" and I'm pretty leary on the brand. I've been getting into MADVR for upscaling my movies to 4K for my 4K TV and it's heavily CUDA friendly, but that's not a deal breaker for me. Also play a lot of Battlefield, so Mantle/AMD camp is appealing to me as well.
 
Solution
Club isn't a bad brand its not known as well as some of the others the 960 and 280 are slower then the r 280x so The r 280x would be the best buy...
