Single core performance or total performance?

it makes sense from a purely practical standpoint- i need to finish off projects to a deadline, and they had been started using a 32bit version of cubase, and 32bit plugins. the increased CPU horsepower lets me do that quicker / with more processing. as soon as i get time off to fine tune a x64 system i can make the switch (which is about a weeks’ worth project in itself). i made the comment however because there is a lot of misconception among daw users who either attribute too much importance to the amount of RAM installed, or to processor speeds vs DAW stablity (whilst they still use x86 software).
