I wanted to upgrade from a q6600 to the new i5 2500k. However, the new Intel p67 chipset, which sandy bridge compatible motherboards are based on, have a major hardware issue. The SATA 2 ports can die prematurely, and also quickly reduce the life of any hard drives plugged into them. Intel has recalled these boards, and the new ones will not be ready until late March at the soonest. Most suppliers have already removed these boards from their inventory as well.
