Difference between these R9 280X

[Jan Bernard Payumo]

There is currently a sale on the XFX R9 280X card shown here:
http://dynaquestpc.com/product/xfx-r9-280x-tdfd-3gb-384bit-gddr5-video-card/

And the one i'm originally supposed to buy is this: http://dynaquestpc.com/product/sapphire-r9-280x-dual-x-oc-3gb-gddr5-384bit/
The Sapphire Dual-X version.
I can see that it's OC and all, meaning it has a little bit more performance.
Other than that, are there any other differences to performance? Does the sapphire card have better performance due to better heat dissipation etc?
The XFX card is on sale, and i MIGHT be able to get it. I just wanted to know the Pros/cons between these two cards so i know which one to buy ultimately.
Since maybe the reason why the XFX card is on sale, is that it has lower performance than the Sapphire card. Thanks!

Well, the biggest pro, in my opinion, is the lifetime warranty that comes with XFX gpus.

Aside from that, it is clocked a little slower than the sapphire card and larger than the sapphire card.

Both should give you unnoticeable difference in performance unless you manually OC to a certain point, if i were you i'd go for the XFX also the dual x OC is an older version if you can go for vapor x oc.
