Dang, $646 AUS!!!! US has it for cheap compared to that price. I think you should settle for a 7800GT then. It's definitely worth it. As good as the 6800GT are, they are getting kind of old, but at the same time, powerful in gaming too. The 7800 series is brand new stuff. I would try to get the GTX if you can, but if money was a factor like me, get the 7800GT.
