I am currently running Nuendo and have recently been taking on larger projects with more tracks. I noticed that my CPU meter in Nuendo is starting to peak out around 3/4 full and my program is running a bit slower. This usually happens when I run some power hungry effects such as the Waves stuff. So my question is, what is the best way to add more processing power to my PC?

I am running a P4 clocked at 2.13mhz with 512mb DDR memory. How much improvement would I see if I threw another stick of 512 in my machine? Or, should I think about upgrading my CPU?

Thanks,
Shane
