Until now I had a Core i7 Beast PC and my 2.26GHz 2009 13" MBP, I am planning to Sell or Give my PC to a Relative because I can't live with it anymore. It's not because it's a PC, I am in love with Windows 7 compared to XP, but It's quite noisy because it's a powerful machine and I feel bothered by it when I try to do something else in my Bedroom, The MacBook almost doesn't exist compared to that thing. I also don't really use it a lot because most of the time I spend on it is wasted on games which I don't play anymore because I'm more of a casual iPhone / iPad gamer than super intensive graphic games and I also have an XBox. My MacBook has 2GB of ram and a 160GB HDD, I feel that when I'm browsing and doing some other stuff I really need the ram, but how much should I get? I was thinking of swapping my 2x1GB sticks to one 4GB one and later add another one if I need it instead of getting two 2GB Chips, does that work? Could I also have a 5 + 1 Config? What brand should I get? Also, I was thinking about more storage, I currently have like 50GB Available but that's because I try to keep out what I don't need, but If I use it as my main computer I will need some 500GB, I was also thinking about an SSD but It's quite a lot of money for 256GB or even 128GB which would be a downsize, will a 7200RPM be way faster than a 5000RPM one?
