Its offering faster than 7950 stock performance so its not too bad actually. It has the Tahiti core but with 2gb/256bit bus. Basically a 7950 version of the 7870XT. If that makes sense.
Please stop being so wrong, and look at some reviews?
It's a Pitcairn XT. A vanilla 7870, just overclocked.
It's not from the Tahiti (7950) family. It's not a Tahiti LE.
It's a 7870 pre overclocked. And LOL at calling it the "bang for buck champion". Sure, if you completely ignore all the 7xxx series cards that are better VFM.
