This is the cheapest I've seen a GTX 680 anywhere. Currently priced at USD $499 + delivery, which comes to about AUD $535 total. It is virtually impossible to find a GTX 680 below $600 locally, and local prices for this particular one are near $700 (excluding delivery!):

I bought one of these cards from Amazon.com when they were first released (paid a bit more than the current price, but still well below local retail) and haven't had any issues at all. The card is great, plays everything on max settings and it came with a free copy of Assassin's Creed 1, 2 and Revelations.
