Macbook Air 2014 unbearable slow

Ever since I updated to Yosemite back in October, my macbook air has been so god **** slow. I can't get **** done on it, and my fans are overheating all the time. When I start IntelliJ, the CPU overclocks itself to 300%, same goes for photoshop. I can't even get anything done on my laptop anymore, and using an exernal screen is almost not worth it because of all the lag on the graphics and overall performance. It feels like I'm using this laptop back in 2008 with 2003 hardware and ADSL internet.

Problem description:

Macbook Air is generally slow, the animations are laggy, safari is unbearable slow and I can’t have Photoshop and safari on at the same time for example without suffering so much lag, and the fan starting to go on.
