This is by far the cheapest price you'll find anywhere in the world that delivers to NZ.
You can check nowinstock.net. B&H, Amazon and Newegg ship to New Zealand, but they add on GST and customs clearance charges. Which means you end up paying over $800 shipped.
This model is one of the most overclockable models (up to 2400mhz on the memory) which equates to additional 6-12fps over the factory "oc mode" (in general about 10% more fps @ each resolution). You can check youtube videos for reviews and benchmarks.

These are MUCH faster and better than any founders edition card. Better cooling, factory overclocked.
I've ordered from Scott before who runs Techworld, and he offers top notch service. You can check his flawless feedback on Pricespy (9.58/10) http://pricespy.co.nz/shop.php?f=11597. He's a good guy, and deserves a bit more support.
Nice, been watching the 1070's (Not buying a new card for a while), hopefully they keep dropping and dropping.
