I have a Macbook pro Mid 2012 with a crucial SSD, 2.7GHz Intel Core i7 processor and 8GB of ram. I use photoshop, indesign, illustrator occasionally, I have a lot of stuff open at once. It seems sluggish, compared how it was anyway. Should I add RAM? Some people say past 8gb it doesn't really make that much difference but as far I am aware it can support up to about 32gb of ram.
