Not to mention that the i7-2600k sold for around 250€ whereas the i7-6700k costs more than 370€!<p>Nowadays for 250€ you can only buy a i5-6600k which is around 25% faster than the i7-2600k in single core performance, but slightly slower in multi core performance due to lack of HT.<p>Only the GPU inside these new CPUs has improved greatly.
