Ok, I have a late 2011 macbook pro that I'm looking to upgrade. It's sluggish with basic tasks such as right clicking to open the little options menu thingy (like the copy and past menu) and minimizing windows and stuff. I mostly just use my macbook for lots and lots of Internet browsing... And I mean lots (I currently have 20 tabs open on 3 different windows of Google chrome) and I also watch quite a bit of netflix and youtube (but when I'm not watching those I don't have it open in a tab so that shouldn't be that big of a problem). So should I upgrade my RAM from 4 GB to 8 GB or should I upgrade my 500 GB HDD to a 512 GB SSD? Thanks for looking!
