Just found this deal for $299. Similar to the 680 deals but brand new and with 3 year warranty. Note this is the 4gb version. Stock clearance! (was $429, strictly while stocks last) EVGA GeForce GTX …
About $70 less than local so looks like the best 670 deal I've seen for a while. They ship to Australia and it's covered by global warranty.
