How many Enzotech sinks do I need to get for Ref 5870 1GB?

[SkOrPn]

Hey everybody, I been searching for hours today trying to figure out how to cool my Asus 5870 1gb, I believe the original version. I got a mcw82, but when I went to install it, I did not see any possible way to remove the current stock cooler as it looks like its one solid piece with the heat spreader. So, I redid the tim on the gpu and was forced to put the stock cooler back on until I could figure out what to do. Ive seen many images of my video card/board, but some show different items/chips to cool and others seem more basic, so for the life of me I cant seem to identify what does and does not need its own sink. Ive called Swiftech and they do not have any more HD5870-HS unisinks, and Ive checked every resource I know for stock and just cant seem to find one. Id had expected someone to sell them, or their used one but nothing at all...

I have a new MCW82, Thermalright VRM-4 and 8 Enzotech ram sinks. Is this enough? Does the memory have to have heat sinks at all?

So, I think I have to install ENZOTECH sinks on it with a fan or two pointing up at it, I guess. Will one pack of 8 ramsinks be enough? Any other ideas that wont cost much to cool my mem chips? Or maybe even dremel my current heatspreader to accept the mcw82 and not have to remove current stock fan or shroud?

Thanks for any help/ideas you can provide.
