Hi all. I have an opportunity to buy a new 1 GB chip of Samsung RAM for my new 1.5 Mhz 17" PowerBook for a total of $259.00. I currently have a total of 1 GB memory in it and I am wondering if it will really make that big a difference to bump it to 1.5 GB. I always subscribe to the theory that more RAM is better, but having just spent a chunk on the powerbook itself, peripherals (wireless keyboard and mouse), plus a 512 chip upgrade...I'm wondering if it's really worth it. I really don't need to be plunking down any more money at the moment...but I am thinking that the price is exceptional...especially for Samsung memory...and therefore, I am torn over what to do. I really don't do any major processor intensive activity as a rule...safari with usually several tabs open, mail is always open, as well as iCal. I sometimes runs iTunes in the background. I use iPhoto and sometimes Photoshop CS and occasionally iMovie...that's about as intensive as it gets. Any input would be appreciated!
