512MB versions of the HD 3850?

I've looked everywhere... Behind the fridge, down that crack at the back of the sofa... everywhere....

Other than the Power Colour card with a heat sink that sticks over the top of the card (and so won't fit) has anyone seen an ATI 3850 512MB version in stock?

Had one on preorder since the beginning of the month and starting to feel like they're as elusive as rocking horse [CENSORED].

They cost around 130 quid plus postage?? You can get an HD3870 for only 10 quid more. Try Dabs as I got one yesterday before they sold out!!
