One word: POWERFUL6/6/2011
I paired the i7 950 with an Intel DX58SO mobo, Corsair h50 cooler, 8GB of Patriot Sector 5 DDR3 1600 RAM, Nvidia 240GT card, 750w PSU and we're good to go. Specs and benchmarking are simply put: powerful. The only downfalls are that it's still relatively expensive and the newer i7's run on 40 less watts (95w instead of 135w). A six core AMD 1050T overclocked comes close to performance but with significant savings, lastly: mediocre stock fan and heatsink. Replace before overclocking.

I bought this for my first complete build in 5 years. I moved up from a q6600 which I had over clocked heavily @ 3.8Ghz. This Processor hits 4Ghz OC on stock volts no problem. I currently have it cooled under a waterblock and at load its 60 c.

Just plugged it and it ran great. What more can you ask?
