PC slow despite good hardware?

Asus m4n68t motherboard

8Gb RAM ddr3

NVIDIA GeForce GTX 680 4gb DDR5

amd phenom ii x6 1055t 6x 2.80 ghz

And who I play Fortnite I have to play on the low settings and reach 45 to 60 fps depending on what's going on in the game maybe it is due to the CPU? Because I see in the game that the gpu is only 42% full

Sorry, but this PC is completely out of date. It is quite possible that the CPU is already overwhelmed, which is why the graphics card is not fully utilized.

So "good hardware" is not. Enormously out of date, especially the CPU. I would recommend you either build a new computer or upgrade to an FX 8350.

What is the graphics card itself?

How is the graphics card too slow for such games

For Fortnite and co. Should it still be enough. It would also cause problems with more complex games. As I said, the CPU is probably the problem right now.

Think get me a motherboard with a better CPU thanks for the answer

I know that but for fortnite it would have to go to max settings or
