Will the 2700K be any less stable than the 2600K?Asus P8Z68-V Pro/Gen3 MOTHERBOARDCM Storm Enforcer Mid-Tower ATX CHASSISWindows 7 Professional Edition (64-Bit) OPERATING SYSTEMIntel Core i7 2700K Quad Core PROCESSORAntec 920 Dual Stage CPU LIQUID COOLING8GB (2 x 4GB) DDR3 SDRAM, 1866MHz SYSTEM MEMORY1536MB EVGA GeForce GTX 580, GDDR5, PCIe GRAPHICS PROCESSORCooler Master 1200W POWER SUPPLY2 X 256GB Crucial 4 High Performance Solid State (SSD) HARD DRIVES -- Raid 1

The 2600k performs very well , no idea on the 2700k.1200w sounds like an overkill.
