Seems a good deal. I missed out on the Sainsbury's deal in the Christmas sales that had it for £499 which was a billy bargain for the spec. My brother bought it at that price and he's really happy with it. I've taken the plunge so I hope it helps someone else who is looking for a budget-ish gaming laptop.
Here is the link for the previous deal http://www.hotukdeals.com/deals/medion-p6624-laptop-akoya-i5-2-53gh/833834
It has a helpful thread about installing the 64bit system as it initially comes with win7 32bit installed.
Can't find many laptops with similar specification for this price and I have been looking quite a lot. Here are some reviews http://www.expertreviews.co.uk/laptops/1281694/medion-akoya-p6624http://www.pcadvisor.co.uk/reviews/index.cfm?reviewId=3255691
Also it does say limited availability so might expire soon but as a plus it does come with a 2 year warranty.
