Would adding RAM speed up my Mac Pro?
I own a 2007 Mac Pro with 2 x 3 GHz Dual-Core Intel Xeon processors.
Probably since moving to Lion OS10.7.3 (now) I have noticed it seems to be slower. Also I am getting more page reloads in Safari (where the page goes white for a second or so then re-loads) This may be that I am trying to do too many things at the same time.
I currently just have 4 x 1GB of memory. Would adding more RAM, eityher an extra 4 or 8GB have a significant effect on the speed? Or has the time come to pay a lot of money for a new machine (either a new Mac Pro if they get updated this spring or an iMac?
Thanks...
