If that price is considered good by the UK members I'd say go for it, even thought I think the KN9/KN9-S is slightly better. Go for the 8600 version you can afford, so you get the DX10 capability. (It beats the pants off a 7600 anyhow; I have an 8600GT/KN9/X2-4000 system and love it.)

One other thing - unless you plan to use SLI graphics, buy the mobo without it if you can and save the money. One excellent card is better than two good cards in SLI from what I have heard around here, and less expensive as well.
