Hi I had a few questions about the i7-2670QM processor that comes in the Lenovo Y570. I was planning on underclocking it to 1.5GHz, which leads to my first question. Will a i7 quad core 1.5GHz be enough for every day tasks and some light gaming? Also, what would the temperature be at 1.5GHz, and what would it be for 2.2GHz (base clock speed). I'm coming from an AMD turon mobile so I am really eager to not average out at about 79 degree Celsius. (seriously right now my wrists are really hot--even on power saver) . One last question--is there an easy way to disable cores? I'm buying this now to have the specs be relevant for many years to come and I don't really need a quad core, so if it would take a few degrees off then I would like to.
