Purchased replacement of a CPU Intel Core 2 Quad Q6400 (grilled CM), I expected to lose some performance but use all goes well, it's related to a newer architecture. The AMD A6 6400K I use mainly for office and multimedia, as well as a few games. These are mostly old but running like a charm on the integrated GPU. I also still plays in Simcity without any discomfort. I wait a bit before getting into overclocking but I do not doubt that it will be simple.
