Hi there, I have a 5 year old Mac Book Pro- 17inch with 4gb memory currently and I've never had a single issue with it. I am updating my Adobe products and I am worried that it has finally reached the edge of what it can handle. I know I can add another 4gb of memory easily enough, but I would like advice on what the best memory cards are (if it matters). Current memory: 2 x 2GB 1067 MHz DDR3 I also want to update the graphics card I think. On the Adobe website they have various recommendations of optimal graphics cards but I have no idea what my Mac could handle or be compatible with. Current graphics card: NVIDIA GeForce 9400M 256 MB (In 'About this Mac', it lists another graphics card 'NVIDIA GeForce 9600M GT 512 MB - I'm not sure what this means and how these work together) Apple store won't help without me paying for a consultation, which I'll do if necessary. But can anyone give me any advice about this?
