XFX R9 280 Black Edition OC Review @ Vortez
 

Aside from a very small boost in clockspeed (reference) and a redesigned cooler, the R9-280 is near identical to the HD7950 refreshed 'boost' edition. Not that this is a bad thing of course because when we tested the HD7950 we were thoroughly impressed. Time has since moved on but with a few driver tweaks and XFX's own speed boosts being that our review sample is the 'Black Edition OC' we hope to see some good figures.
