As it's cherry picked.
Ok then that particular HD6970 came pre-overclocked as well. I'll just say that was cherry picked as well then. It still doesn't make it better than the GTX570 when overclocked.
Anyway, here's a small list of what people have achieved: http://www.overclock.net/nvidia/891918-gtx-570-overclocking-thread.html
The cards have quite high overclocking headrooms at voltages less than 1.1V
. While technically true that it's pre-overclocked, imho, it's not a fair comparison.
just seems to excel in performance in everything I throw at it
