Hi, I own a G5 desktop (2004) running CS3 and MacBook Pro (2006) 15.6" 2.16 ghz Intel Core 2 Duo. I want to upgrade my CS3 to CS5 but can't on my G5 since it is PowerPC, so I want to try it on my Intel based MacBook Pro instead. I can upgrade the memory to 3GB, but wanted to know from other users out there if Adobe CS5 will be super slow or could even work ok with my laptop? I'm trying to save a little money and time before purchasing a new intel desktop. Thanks in advance!
