Hi All I have a 1.83ghz CD macbook with 512mb of ram. I am finding that it is begginning to get really slow i.e (with nothing else running)it will beachball for like 8 seconds before it opens safari, etc. I reformatted a few weeks ago and it seemed to speed things up but now it seems to be back to its slow old self. I was wondering if I should upgrade my ram to 1 or 2gb. So I have the following options about upgrading my ram: - Buy 2x 512mb Sticks - Buy 1x 1gb stick and keep my other 256 stick (Is this advisable?) - Or Buy 2x 1gb sticks I am only 16 and really want to get a new iPod touch next week (if they are released) but also need to upgrade my ram in my laptop. What is this ram like is it of a good quality? Transcend JetRam 200pin DDR2-667 1GB SO-DIMM Any thoughts, Thanks?
