I just read a review on Hardwarezone (http://www.hardwarezone.com.au/reviews/view.php?cid=6&id=2191)
With all those copper heatpipes, I doubt $140 is realistic. The article mentions $200 Aus. which works out to about $175 American.
I just re-read the article and it mentioned $200 - $220 US
Personally I will wait for the 650i Ultra, as I'm not into gaming. Hopefully it will not be some cheap stripped down thing.
I'm also considering the GA-N650SLI-DS4 (Gigabyte) or it's non-SLI brethren
