I've got a mid 2010 13" and it runs fine but I'd like to get another two years out of it. Was wondering if I would be better off upping the ram from 4gb to 8gb or getting a better HDD? I currently have the stock 5400rpm 250gb HDD. If I could find an SSD for under $200 I would do that, but otherwise might have to opt for either a 7200rpm drive or a hybrid. At this point I'm thinking of just starting with the 8gb. I'm mostly looking to improve load times, especially with some games. And on that note, what kind of RAM should I be looking for these days? Suggestions? Thanks!
