Intel extreme processors tend to be about £560 ex taxes. when they come out. Vendors tend to stick close to intels recommendation for the extreme, you get more variance on other parts. There are of course exceptions, the extreme QX9775 is going for $1650 ish before taxes and with taxes it weighs in at over $2000.
The problem being that we pay more for the equipment and then more in taxes too!
We also have to wait patiently for price cuts too, when a manufacturer announces them you can normally find them on a US site for that price in a couple of days, over here it can take weeks or months. Although that would be due to being a smaller market/ individual site inventory levels.
