That was an interesting benchmark comparsion. Deja vu like.
I skipped the 5 series as I decided to keep my 4870 for another year.
If i had a 5 series I'd laugh at the 6 series for quite a few reasons.
However I've come from a 4870 to a 6950 that has unlocked to a 6970 and my opinion of this card is both over the moon and disappointed.
The performance I'm very happy with, the power requirements i'm ok with.
The fact it unlocked and comes with switchable bios !!! Genius and stonking value ,, the thermals not very pleased with though , and the driver support is always behind on schedule and then your left wondering if cat 11.1 will improve performance.
I still call them by ATI , like coco pops were renamed Choco Krispies, no ****ing way i called them that, and my last one Starburst, nope they are Opal Fruits.
Amd to me have lost their edge, the bite and my faith a little.
A long time has passed since the socket 939 days, and we all know what failures and disappointment the phenom brought. It was so bad It made me turn to intel for the first time in my life !!
The phenom II was a success but it was a bit too late, I'm not knocking the pII but the original phenom should have been as good the first time around.
Thats how I summarise these 69** cards
Amd/Ati (for me its ATI

have made a phenom 1 again on the basis that they are at thermal limits/power dissipation on the process and so have had to cut a lot of performance off to make the product marketable and functional.
I wish the 69 had been made on 32nm instead we have to wait for 28nm. It will be interesting for both amd and ati this year, as we are waiting upon Bulldozer and Antilles .
The 6950 still didn't stop me from buying it, massive gain from a 4870 512mb and I was lucky to unlock it and have it stable.
Now we just need some development in pc gaming to make use of our superior hardware to the console boys.
