Summary: Well worth the $$$. No need to overclock, already runs at the great speed! Only one thing I can complain about. The stock fan is terrible! Get an aftermarket cooler, costs $30, lowers the temps dramatically.
Summary: I overclocked this processor on the stock heat sink and fan combo to 4.0 GHz while maintaining temps <70. I dialed it back to 3.8 on stock voltage until I decide on a cooling path. CPU performs as expected. Integrated HD 4000 graphics works well enough for Steam, light video editing with software encoding, and standard desktop duties.
