I am interested in purchasing the Intel e2160. I have read that the M0 stepping is better for overclocking (runs cooler, etc.). I am looking to OC mine to 3.0ghz on stock cooling (and wishfully stock voltage). ClubIT is out of e2160s with MO stepping at the moment. Should I wait for them to come in stock, or take a gamble elsewhere? How big is the difference between L2 and M0 on this chip for overclocking? Thanks in advance.
