guys im getting the intel build thanks for helping me on this one.
EDIT.just asking there is a 4.20ghz and a 4.40ghz which one should i go for http://www.overclockers.co.uk/showproduct.php?prodid=BU-035-OB&groupid=43&catid=339&subcat=
and http://www.overclockers.co.uk/showproduct.php?prodid=BU-039-OB&groupid=43&catid=339&subcat=
As I said above - the 4.2 gets you down £35 closer to what you wanted to spend, or the 4.4 gets you a better mobo, better cooler and of course the extra 200MHz squeezed out of the CPU. Worth it imho if you can stretch to it. If you upgrade to a quad core CPU later I'd be worried about overclocking it on that UD2 mobo in the cheaper bundle as it has no MOSFET heatsinks (that little piece of advice by the way came right from one of the OCUK guys in another thread

Up to you.
