I currently have 4gb ram, 500GB hardrive i7 Macbook pro that I bought back in April of last year. I've been noticing that it takes a while to start up photoshop and other applications so I'm looking to upgrade everything this year. Technology constanty changes so fast that I didn't want to rely on months old information that came up when I googled and thought I'd ask here. What is the best 8gb ram out there currently? and SSD? What is the maximum SSD space available? Are there any other updates that I should do along with the ram and the SSD harddrive? Thanks! Btw- I have a battery that's at 95% after only 40 life cycles and it only seems to last me 2~3 hours. Do I need a new battery?
