Looking for peoples oppinions on something that i have done ever since owning a pc. Ive allways had a thing about reformatting my pc, i love the fresh install as it feels so nippy and clean, but what impact does this really have on gaming? when your pc feels clogged down with all the crap youve gatherd over the past year or so do you feel a performance boost after a fresh install of your OS or is it all in your head?
