Which Sapphire R9 270x should i get.

[DrCrippinz]

Looking at buying a new gpu sometime soon. And the 270x is perfect in my price range. However i have been looking at three different ones from sapphire, they all seem very similar and don't know which one i actually want to get. I will link all three from Amazon. The last 2 are the ones I'm most likely to pick. I just need to know which will perform best and reasons why please.
Sapphire Dual-X R9 270X
Sapphire R9 270X 2GB Toxic
Sapphire Dual-X Radeon R9 270X OC

Get the cheapest one. They all will perform equally.
