On amazon there are the powercolour and the vtx3d versions but they are the same type of design and more pricey than the clud3d one
The only one with a different design is this sapphire one. Its about 20 pounds more and offers a better cooler.
The cooler on the clud3d version is fine and all but the sapphire one does cool better
depends if you feel like slightly more OC room [if temp limited] and and cooler card is worth 20 poundshttp://www.amazon.co.uk/Sapphire-11199-20-20G-CrossFireX-Multi-GPU-Technology/dp/B00AX2ONI0/ref=sr_1_1?s=computers&ie=UTF8&qid=1363379200&sr=1-1
Pretty hard OC does stretch the cooler to it's limits
