I will be using my computer for online english classes. I will be opening a lot of windows and applications (two Skype accounts, QQ, lots of tabs on Chrome, OBS recorder, notepads and a custom application from the company). I will also play a lot of games like GTA 5 and Witcher. I'm wondering if it is a good choice to get a 6700k because of those reasons? Or would the 6600k be enough for shifting applications smoothly?
