again to the TS you can listen to a speculation by a self-proclaimed hardware guru who calls people troll, that seems to have little to no attention to detail: e.g. cannot differentiate between what "can handle" vs "handle smoothly" means.
well just be prepared to stuttering when scrolling down web pages if you'd go with a celeron (scolling from the top of this page to the bottom spikes 60% usage using opera).
peace out.
