Reinstallation of Windows 10 has caused CPU usage to dramatically increase.

Due to some hardware upgrades and limitations due to knowledge and software, I reinstalled Windows 10 on my desktop, while upgrading to some better SSDs that are now in Raid-0.
This was a simple enough process, and I was reinstalling basic software and eventually got to games. When I started playing them, I noticed that my CPU usage was much higher than it was before I reinstalled Windows 10. A good example is that I was running GTA V Online around 20-30% usage, and now it goes up as high as 60%. Open Broadcasting Software went from around 10 to 25% usage. The list goes on, but it's pretty universal for most programs. Is it possible I've missed some software related to my CPU that would cause this problem?

Previously used:
Windows 10 Home
Hard Drives: (boot) 80GB SSD, (storage) 2x 300GB 10,000RPM HDDs

Just installed:
Windows 10 Professional
Hard drives: (boot) 2x 500GB SSDs, (storage) 2x 300GB 10,000RPM HDDs (Same from original)

Everything else remained the same.
Intel i7-4790k
Nvidia GTX 980
16GB RAM @1600MHz

If there's any other information needed, please let me know. Little new to posting on this site.

I would say testing it would be the best way to tell. I have run a RAID0 for HDDs so I had large space on the Intel RAID for years but since it is always a secondary drive it never affects my CPU but since it is a combination of software/firmware RAID it will utilize some CPU cycles to do its job.

I did actually use the Intel Raid setup (accessed via BIOS) for my two new SSDs that I'm using as my boot. I'm not sure I'm alright with that high of usage. I generally like to run a few various programs at the same time and, while my temperatures are never a problem, I have been finding myself capped at 100% from the sum of the programs pretty frequently. Usually the list includes the game I'm playing, some chat service, Skype, and on occasion OBS (Which is the one that caps it). Would I be correct in assuming that I'd have to drop the boot out of Raid to get the desired CPU usage results?
