Hello. I just upgraded to Snow Leopard (WHEEEEEEE!) and would like to know: Is it possible to upgrade my iMac (24", 2.93GHz Intel, early 2009 model) and my MacBook Pro (15.4", 2.66GHz Intel, early 2009) to 8GB so I can make better use of After Effects CS4 for rendering? (even if AE CS4 is still limited to 4GB net, that still leaves 4GB for the OS and other apps - no biggie either way.) Thx!
