I want to buy the most basic alienware setup. The price is 1699. The processor is a i7 5820k. this is the 6-core processor overclocked to 3.8 ghz. I separately want to buy a i7 5960x. Alienware overclocks this to 4.0 ghz. With all that out the way... will I be able to buy the latter processor and overclock it myself to 4ghz? Or does alienware overclock it some type of special way?
