I have a 15" Macbook pro that was released Feb 2008. I currently have a 320 gb 7200 rpm hard drive and 4 GB of ram. I was debating about upgrading the machine to 6 gb ram and buying a 256 GB SSD drive. I currently am using 200 GB on my hard drive but have a lot of movies and some could be moved to external. So should I invest close to a $1000 (if I got the fast Samsung), buy a new 15" macbook with the newer config or just be patient and wait? Also, will the SSD HD decrease the heat and noise? Got Coolbook but still warmer and noisier than i would like.
