sorry but you would be dense if you didn't overclock a celeron, you would have nothing to loose, anyways there good at it, simple put, between netburst and K8 i notice absolutely no difference really in games, maybe few FPS but thats nothing important if your already getting 50 or something, semprons, athlons, opterons = over-rated IMO. (i know someone will say 'well your just stupid', but its just what i have noticed with mates pentium IV and my athlon, theres absolutely no noticable difference, he uses ATi graphics, i use nvidia, still no difference unless your so inconcievably picky
