Just incase anybody is looking for a rev 3.3 of the DQ6 then I've just brought mine from here

The rev 3.3 is the only version to do 1333mhz bus speed, and from looking at reviews it makes quite a difference!!
Prompt delivery, smooth and easy to use site.
After being promised a rev2 by other sites and receiving a rev 1 from dabs I found these advertising the rev 3.3 for the same price. So i returned the rev 1 to dabs and i'm over the moon now
