I agree if you live in Australia.
I live in Canada, when this card appeared for pre-order 2 weeks ago I immediately put 2 in the shopping cart. DHL international would ship it to me for approx 30 pounds ~= $60 CAD.
At 499 pounds to CAD that amounts to $919.98 CAD. Then I will pay duties, roughly around 13-15% putting this at 1039.58. Taken together, the final value is approximately (as the duties are somewhat uncertain), $1100+ CAD. The expected minimum total where I live would then be $2200+ for crossfire.
I then emptied the shopping cart and pre-ordered two of the 4gb OC versions which feature a faster core and mem clock on Amazon.com for $659.99 USD a piece or $745.79 CAD.
Total price is $1319.98 USD or approximately $1491.58 after approximate duties. Shipping cost me $30. Total cost is then roughly $1525 CAD, a difference of $700.
$700 for an extra shared 4gb of vram, slower out of the box clocks, and the uncertainties of international overseas shipping makes this a no-brainer.
That means, for me, the extra 4 gb of vram in crossfire is not anywhere near worth the price.
I should just SLI a couple of Titan-Z cards to be "future proof" .... sarcasm included at no extra charge. Come on Nvidia really $3000, I mean the 780 Ti is definitely the hands down best single gpu solution, but the Titan-Z? Does it come with beluga caviar, champagne and a plaque? Do people have to kiss your ass as the default greeting upon learning you own one? Ha Ha Ha ... I laugh at my own jokes... sorry.
