Basically... i have enough cash for a new graphics card 
Iv'e got about £150 to spend, and iv'e narrowed it down to these 2.
Iv'e picked the 4890 because i'm not really interested in DX11 etc. etc, so i just want the most performance for the money.
I think for the price point.. these two cards are about the same?
I just want some oppinions on which one to get between them
Thanks in advance!

it will outperform all 4890s at that price point and will generally match the top end overclocked 4890 models - its roughly equivalent to a 1GHZ core 4890*.
