like i said. it depends on what your doing. if your just gaming, then id say you dont need to overclock it. but if your running a real high end gpu, or 2, then overclocking would be good to eliminate any bottlenecking. or, if your doing media editing, with like transcoding, or adding effects, then an overclocked i7 would be great to have as it will get the job done faster. other than that, there is really noneed. and for you sonce you are just gaming, then 3.5Ghz with its 3.9ghz turbo boost mode, id say you are good to go. no worries
