I received mine last night, I also signed up when they announced the whole thing. They are a bit different than what it was shown on early videos...now we have 3 more strips for the vram as well and the thermal paste comes in a plastic little case. The process is straight forward and it is not hard to do.
That said, the led connector on my card was pain in the butt! It took me 15 min to unplug this sucker...I don't know what was wrong but it wouldn't move...I did it and did the mod and then my led's stopped working, had to wiggle and re-plug it to make them work again...be careful with the led plug(the little one) it is fragile and extremely hard to unplug.
But I am glad I did it...after the mod my core temps went down 6C. Awesome!
