Thanks guys, I appreciate all the helpful comments. Really helps me feel comfortable with my purchase.
matto17secs, my brother will only know he can run sc2 on high/ultra, he won't know what I can do :P
I found these reviews which helped me too, incase anyone else needs something. This isn't for the exact gigabyte one I'm going to order, it is for the one that isn't overclocked already: http://tbreak.com/tech/2010/11/gigabyte-hd-6850-review/all/1/
Also this mentions what the Ultra Durable VGA and Windforce do for the card: http://www.pureoverclock.com/printer.php?action=review&id=1109&page=4
I'll let you guys know my final purchase and update on how the card works out. Thanks again!
