CPU usage

hey there, ive got a little problem with cpu usage when i have VST plugins working. depending on what imdoing it runs between 50 to 100%usage and obviously lags and stutters. ive upgraded to 16GB ram but it makes no difference. i use FX and Group tracks to lighten the load but it still peaks!

any help??
