My spec on my MPB 2011(early) is 2.7 GHz intel core i7, 16GB ram( which i upgraded from 4GB), about to swap out my old HD for a Samsung Evo 850 500Gb SSD. I want to know is it worth it for all these upgrades because I was going to also install another Samsung Evo 850 500gb SSD by replacing my optical drive( since I never used it ever). I notice that the MBP 2011 (early) have only one fan compared to the late one. Like many other 2011 MPB user, I have a heating problem as well. Even doing simple task like browsing the internet, sometimes my fan would run at a high RPM (making extremely loud sound). That problem kind of clear away when I upgraded to the higher RAMS, but sometime it still heat up and make a bit of sound. So should i continue with all these upgrade with the 2 SSD or should I just buy like a mid 2012 MBP?
