Features Key features of the Radeon R9 280  vs HD 7950 Boost 

pixel rate Number of pixels a graphics card can render to the screen every second

Radeon R9 280
26.5 GPixel/s
Radeon HD 7950 Boost
27.2 GPixel/s
The Curacao Pro ended up faster than the Radeon HD 7870 in a previous performance overview so its easy to say that the Curacao XT based R9 270X would be much faster and trade blows with the Radeon HD 7950.

Wow you are not kidding with them re badge this graphics and the problem is that the 7950 and 7970 have gone up so much in price it makes it hard justifying spending 400 on a 7950 when I can get a 7770 4gb and or pay 80 dollars more and buy myself a 780 or a 280x. I wish AMD had done things differently for these cards because right now I am trying to build my wife a newer and better gaming rig compared to her aging anthlon 4 core. She mostly plays WOW and she is a hardcore raider and in 25 man when you are a healer you cannot be getting lag and bad framerates like she has been getting. I was wondering for 220 limit what would you recommend for a gpu that can handle play the next expansion of WOWs graphics at 1080 during 25 man raid?
LOOOOOOL
why wait so long to just release a re badge amd disappointing!
