I am looking to save some money and rebuild an old computer rather than spend the 2000 on a new one. I have a late 2008 MBP that has lasted quite a long time and obviously performs at a much more sluggish rate. Im curious if I could restore some of its power by replacing the existing hard drive with a SSD and adding 8Gb of ram. Or would it still be slow since the processor and the rest of the internal parts are old?
