Off my advice, having experience of the cooler, Buddy ordered one of these last month from an Amazon store in the states for $520 (equiv £365).
Takes just over 2.5 slots, effectively 3. The ram has been cooled (which I wasn't aware of, must have been an after thought, even tho it's just a sink the 2 fans cover it).
Idles @ 42 degrees, ramping to 72 degrees maxed out on stock (the oc stock of 756). Not someone who would oc it tho due to tight panties.
Best of luck finding many reviews through the red mist, it's an awesome card, but retails in the UK anything from £470 - which is shocking imo. Almost £110 over priced, I bet you could internationally ship it for less than that.
