Core i7 is definitely the fastest CPU on the block, but when it comes to sales, it is not doing particularly well. Despite the fact that the cheaper Core i7 920 sells for a reasonable €260 for a 2.66GHz quad-core, motherboard and memory prices are the reason why customers shy away from this platform.

Core 2 Quad is still performing quite well, and the motherboards are cheaper, not to mention the memory and most of the customers even today tend to go for a Core 2 Quad rather than a Core i7.

This surely has something to do with the economy, as nowadays the cheapest X58 motherboard sells for a reasonable €177 or more, but the guys who are selling these CPUs confirmed several times that Core i7 is not a top seller.
