a 1Ghz 7850 is all good and in all fairness another 50Mhz does not really amount to much at all if anything. At 1Ghz the 7850 will consistently outperform a GTX 570 so I would leave good enough alone and good play some games and enjoy the card.
That's my opinion, too. Just bumping up to 1000, pretty much gets you 7870 performance for free, so just be happy with whatever you can get. Some people try to get as high as they can just as a hobby in itself, but diminishing returns certainly kick in fast.
