I bought this from Newegg for $1100 and only used it for a couple months. It's way over my budget at the moment, hence I pass the savings on to you. The base frequency is 2.0Ghz, but I've never seen it run lower than the all cores turbo speed of 2.4Ghz. You can run this on any consumer X79 board, but it's also compatible with dual socket ones.**Does NOT come with a cooler**-C2 stepping so supports VT-d-Overclocking only supported through bclk (?5% realistically). No multis or strap ratios.Cash onlyShoot me an email and I'll get back to you as soon as I can.Thanks for looking!-Mike
