Im not really into intel,my main rig is an amd,but i think that celerons cant be oc'ed,and pentiums i think you can but not that much,the only pentium that could go crazy high with overclocking was g3258. If u are looking for a home pc,not gaming u will be fine with celeron,but i'd still reccomend the pentium,since it gives u a lot more horsepower than the celeron.
