That is a good deal there but in gaming their isn't much of a difference between the 2500K and 2600K so I would go for this bundle its £319.99 inc. VAT and comes pre-overclocked with a after-market cooler, same motherboard and mushkin ram and free shipping for today. bundle
The UD3 nd the MSI boards in those bundles are low end and although the RAM in the UD3 bundle is decent the Mushkin has better timings and if it's for gaming you only need 4gb. Also no clearance issues with CPU coolers and the Mushkin RAM either.
