I don't understand why anybody buys Intel CPUs. The newest Intel CPU (6 cores, 3.6-4 GHz) costs more than the AMD FX-9590 (8 cores, 4.7-5 GHz). ???
Intel uses much less power/performance and puts out much less heat (look at TDP). Also, the high end i7's perform MUCH better than the high end FX octo cores. Useful in laptops and beast rigs. AMD is the budget king however. If you don't your computer sounding like an F-18, go with AMD octo.
