I think HBM supply is preventing them from selling a ton of cards. I was really hoping AMD had some version of Fiji that could utilize GDDR5 as a stop gap measure, like a mobile Fury designed for laptops but retrofitted for desktop use.
Not a complete surprise, the Fury X's launch did not impress most people because it was handled poorly. Performance was muddled by driver version confusion, and it was almost essentially a paper launch due to low HBM supply. Even now the Fury X is still not an easy part to find in stock.
I think overclocking will be extremely limited because it doesnt have the power connector.
If I remember right, at stock speeds those 'GREEN edition' cards were nearly using all the power the PCIe slot could provide.
It's a fake GTX680. It's really something like a GTX650ti, with a modified bios to mis-represent itself. (SOURCE)
That cooler couldnt even keep a GTX680 cool, and there is a reason you don't see the power connectors.
