£15?? Where'd you get that from? X2 3800+ is £105, E6300 Retail is £152 - the OEM is £135 plus the cost of a cooler, which the guy above suggested £17 - that's £47 straightaway. Then there's the issue of motherboards costing more, with something like the MSI AM2 K9N 550 being around £58 for a good set of features and available slots - with Intel boards your looking at £88 or more (the ASUS Micro ATX is cheaper, but then it's not got great features at all IMO), and then some of the things such as audio codec look a bit iffy. Altogether, that would be about £77, which as I said, somebody on an ultra budget like me would go for.
