Just as a Update - I asked this question on other forums (for the wide range i thought of replies) and also mates on email - every single person said the same thing - "Build it yourself".
At the mo Im waiting, cos i dont want to buy a 754 system, would rather have a 939 socket (for pci express etc) but Im not happy with the 939 a64 chips, half the cache, roughly the same speed as 3400 and a lot more dosh to buy (in the scheme of things).
God why do Intel and AMD keep giving me choices....suprised no-one said buy a apple yet
