I recently purchased my Alu iMac (lower end model, 2 GHZ 1GB Ram). Thats all I THINK I need, but it got me thinking on wether or not I should upgrade my RAM. I'm going to have this computer for 5 to 6 years (maybe even more if it lasts) and am wondering if I should upgrade my RAM from 1GB to 2GB. Is it worth it? Will it make my computer faster? (Im guessing that's what RAM is for, letting you run more programs faster) People say it makes a big difference, and I mainly go online and use my Mac for gaming. Is it worth the cost?
