Gabe - I tried my MCW60 on my 5870 last week, and found it made v.poor contact with the GPU. I fiddled around with it a bit, but it would only contact one small part of the GPU. Not sure if the GPU is a mm lower vs. the shim or something, or do we need a new mounting bracket for this card? BTW... glad you are doing a full heatsink solution for this card, hopefully it doesnt take too long to land over here in the UK!
