I just bought a refurbished MacBook Pro 15" C2D Penryn from apple for a great cost included with iLife '09 and Leopard which was a great surprise as I expected I would get the software that came with the computer at the time. Anyways to my question. With a refurbished machine I was unable to customize my ram and hard drive. My mac came with 2 GB of ram. I have an opportunity to purchase 2x2gb of ram for $70. I own a small business and use my mac primarily for spreadsheets, documents, iPhoto, kinda getting into iMovie since I own a camcorder. I do however play Call of Duty 4 in Leopard and Battlefield 2142 in windows using boot-camp about once a week. A year ago $70 wouldn't be a big deal. My ego would love 4 GB but would I benefit enought to justify the purchase or am I throwing my money away? Also as ram keeps going down in price would I be better waiting and buying later? Also another question that is unrelated. I have heard that my mac being MacBook Pro 4,1 can take up to 6GB of ram. Is this true. On apples site it say max is 4GB of ram. I'd love to hear your thoughts.
