You guys are scaring me...I just ordered the 7970 Gigabyte edition and it comes hopefully tomorrow. I only ordered the darn thing cause it said it got 769K 
Why is that scary?
Cause some of your numbers are really off. 650 isn't acceptable for a $450 dollar card. You can spend almost 200 less on a 7950 and get 650. I am guessing it is just a wrong setting. Even my nasty old 6850 is pulling 260 and its only reported for a little over 200.
