Intel Q6600 the quad core at 4x2.4 GHz or should we be precise and say 2x2 cores at this speed dropped below €250. This was part of the 22nd July price cut plan and this is by far the cheapest quad core solution you can buy today.
American and European processor list price is $270 and we expect that this quad core will get a bit more expensive at least in America due to margins that etailers and retailers need to make.
In Europe you can buy them in few shops for €250 and get them delivered to your doors for a few more Euros.
You can get them here.
