ok obviously the e6550 C2D is a higher number but is it a better pruchese then the e4400. the core speed diffrence is 1.33ghz but the bus speed is 800 on the e4500 and 1333 on the e6550. I would purchese the e6550 but why is it e6550? it migth be a dumb question but im just wondering because usaly things with a 50 on it mean like its half as powerful then the actual like thing (i.e. nvidia 6150 vs 6200) which do u think i should purchese?
