Well having convinced myself that the GA-X48-DQ6 was the only board for me I have now discovered that the previously unobtainable EX38 boards are now available, though still not widely yet.
So this brings a new dilemma. My choices are:
1. Gigabyte X48-DQ6 @ £200 (available in store)
2. Gigabyte EX38-DQ6 @ £166 (web purchase only)
3. Gigabyte EX38-DS5 @ £128 (available in store)
Now my obvious choice would be DS5 and save my self £72 but other than Quad Bios (not necessary I think) a couple of capacitor changes and the crazy cooling for under the CPU, which I would need to remove anyway to add the water cooling, IS there any real benefit over a DQ6 model to that of the DS5
