Gigabyte GTX 960 OC 2GB OR Sapphire R9 270X 2G?

[Forezza]

There is a sale on around my neck of the woods and these are quite similar prices. I've seen that the GTX 960 is quite similar to the 270x in the speeds on http://golubev.com/gpuest.htm although the SHA1 speed is faster and MD5 is slower. My question is, what would be better for hash cracking as a card from the lower end of the high range cards.
