Sorry if I sound like a shill for Dell, but if anyone's looking for a new high powered machine and don't want to pay full price, I got my new machine from the Dell Outlet website (http://www.dell.co.uk/outlet - and I think there's an equivalent in the US). It's where they sell all their returns, misorders etc, and while you have to be quick (it's first come, first served, so the best machines might only be on offer for half an hour or so before they're snapped up), you can get some real bargains. My machine cost 1500 incl Vat, and when I priced the machine on the normal Dell site it added up to around three grand. It runs the demo on everything Ultra and max AA etc.
