I just got one of these and unless I'm mistaken about my system being perfectly stable, then they clock like mummy lovers!
I bought the BFG Maxcore OC version but was going to return it and buy one of these XFX Black Edition ones, due to their very high factory overclock.
But before doing so I tried overclocking mine and it reached that level, seemingly without any troubles.
I then went all the way to 700 core/1475 shader/1200 memory. I would have gone furher but apparently higher overclocks don't take effect?
I ran 3DMark06 on a long loop and there was no artifacting or crashing. Going to set up a longer OCing test tomorrow but first impressions are very good!
