It will be interesting to see what the memory bandwidth does for performance, I feel like it will be a mixed bag in Games, office suites/data would see the largest gains.
Oh, also Kyle, I was going to ask if you thought about mounting the water block the other way. Even with the water spreader, there is more water flow directly in line on the channels from the inlet. And if you rotate the block 90, then that channel would be right over the entire CPU under the heatspreader. Which on a smaller die isnt a big deal, but the 8600/8700 dies are rectangle in shape.
I have the non-mini version of this board and (what I though was excessive) some Dominator 4000. XMP makes my temps go through the roof, but just inputting the values manually works flawlessly. So far so good at 4.8GHz. I'm sure I could probably hit 5GHz, but I don't know if I'd see any benefit to justify the extra heat/noise.
