Arch_Angelos :
NZXT's cam is much better than MSI's afterburner. https://camwebapp.com/ I've got both and afterburner is primarily for over clocking and not monitoring the system like cam is.
Afterburner comes with Rivatuner Statistics Server which is only for system monitoring, you need to heavily monitor your system to OC it.
I've also been seeing quiet a few people for who the CAM software has been crippling their computers with stuttering and low usages.
This isn't the first time I've seen the OP comeback and say uninstalling CAM fixed their weird issue: http://www.tomshardware.com/answers/id-3160928/50fps-csgo-980.html
