My cpu is at a 100% utilisation while my gpu is only at 30%

So I'm not that good with computers but I think I know the problem but I'm not sure if this is actually it. So I never really played a lot of games on my pc since I'm a console player, but I decided to play a bit of fortnite on my well-outdated pc and I was averaging anywhere around 20-29 fps (no there was no fps limiter). One day I was on youtube and I saw a video where the person in the video said if you have a bad pc with an old CPU just throw a budget GPU in there and it should give you higher frames. So went online and looked at some cards that were in the low-end budget section and came across the RX 560 4gb card from sapphire. It was fairly cheap (£125.00) so I picked it up. when it came I put it in my pc and I connected my display to the GPU and I still was getting quite a low amount of frames. So then I was like what a waste of money, I then looked at task manager > Performance and saw that my CPU was at 100% utilization while my GPU was only at 37%. like I don't know much about computers but this seems weird. If you're wondering what my

PC specs are it's:
AMD APU A6-6400K Black Edition Dual Core 3.90GHz
Gigabyte F2A68HM-HD2 Motherboard
Corsair CP-9020097 550 W PSU
RX 560 4GB Sapphire Pulse

If there is anything I'm doing wrong please tell me, because right now the only thing I can think of doing is buying a quad-core CPU. The only thing that made me stop is when I looked at the fortnite min specs. on that spec sheet, they also suggested a dual-core CPU.

Nothing wrong with your 6400k but you need a 4-core processor with that rx560 as the card is too demanding. This is the best for you: £38 https://www.ebay.co.uk/itm/AMD-A10-5800K-3-8GHz-Processor-For-Socket-FM2/123121088200?hash=item1caa96b6c8:g:uEIAAOSw4RZa8NHH

Try it without the card first as its inbuilt graphics is reasonable. The following two 4-cores are £48 with not-so-good graphics but similar speed to the one above:

The Athlon x4...


According to CPUBoss it wouldn't really make much difference http://cpuboss.com/cpus/AMD-Athlon-X4-860K-vs-AMD-A6-6400K

But, I would run something like ZHPCleaner, to make sure you have no malware running.
Kill off any tasks you don't need running in the background.
It is worth trying if you can find a cheap second hand one.

The Athlon x4 860k is the same as the others but has no graphics so isn't so good. It's weird because people use fm2 motherboards because they want processors with built-in grapics.

I've read that fortnite runs well on 4-core processors with the rx560.
