Here you go, silly money...http://www.memory4less.com/m4l_itemdetail.aspx?itemid=1453725275&partno=100282-2GVXSR&rid=fd_10
Just because you can't find cost effective 5970s doesn't mean they don't exist. I have noticed how every thread involving a 5970 you make comments about the person throwing the money away, getting ripped off, should have used 5850s, and dual GPU are for clueless people.
The reality is there 5970 is one of the highest performance per watt cards AND can be obtained for low cost per MH (at least by some people) AND has extremely high density. A win-win-win.
I haven't seen a 5970 *anywhere* in the UK for anything approaching reasonable money, certainly NOTHING like what the Americans seem to be able to achieve.
As to Messy's profitability / etc., I have no dog in this fight. But in the UK, the most cost-effective cards at reasonable prices (and you can't ignore availability here - having one card in the entire country doesn't make for cost-effective mining when you have to wait months for stock) are the 5850s. Specifically, the original retail Sapphire 5850s - not the Extremes (on this point Messy and I disagree
). The 6950s are approaching this too, but need all sorts of tweakery.
The main issue in the UK is availability, and this drives up the cost of dual-GPU cards to uneconomic levels. If you can find me a card with good availability in the UK, plus a price close to the prices you pay in the USA, then I'll agree with you about the 5970s. But I don't think you'll be able to find a source.
Remember that if we import from you, we get import duty and then 20% VAT bunged on top of the cost of the card, delivery AND duty.
Not wishing to continue a pointless debate, but just because we speak a similar version of our language, doesn't mean that we have the same access to technology at the same prices... even the stuff we design and build is cheaper to buy in the USA. There's a well-used phrase over here - 'Rip-Off Britain' - and it's not overly hyperbolic...
