Graphics Card Choices

[Gerbil Maximus]

Hey all its looking like my GPU is on its way out, so im looking at getting a new GPU.

I'm googling to get reviews but I'd like some feedback on the cards listed below if anyone has one of them, as they are all within my price range.
Also your own opinions on which one i should get would also be welcomed.

That shop doesn't behave well with cookies disabled, I'm not interested in going there twice.

My 6850 gpu is the same as a 6870. So it's pointless to buy a 6870 as you can set your 6850 clocks exactly the same as 6870.

I just bought a 6950 and the performance difference is brutal.
AND it comes with 800Mhz stock clock, and I'm using 920Mhz with no mods.
