no if your useing 2 cpus in to cpu slots that would create a lot of bodel neacking
the intel core 2 quad is to intel core2duo chips yes but there so close and on the same chip that there basicly is no bodelnecking problem but
if your have to cpu on to diff slots
the bodel necking goes way up
this is offcourse if your using this as one pc like playing games ect...
but if your running a server is makes no difference becouse the data does not have to be split up like if you were playing a multicore application. a server would just put on job in each core
