I'm considering adding more ram to my quad core mac pro (2010 tower), does this will affect pro tools (I'm running hd12) performances? any experiences to share?
How much do you have now? Do you use disk cache feature in Pro Tools?
RAM is 8Go at the moment, cache is set at normal, can be set up to 5Go
8GB is fine for most recording / mixing duties. 16GB or more becomes handy when you use a lot of sample based virtual instruments. I've got 16GB in my iMac but my sessions run fine on my Macbook Air with 8GB.
