Question What parts of my PC are the problem to low performance?

[andrew.s.omalley]

The main game I play is fortnite, as well as edit videos. I recently got a 1660ti Graphics Card, and I'm not sure why my performance has not increased that much. My Specs:
i5 6600k
8GB DDR4 2666MHZ
GTX 1060TI
650W Power Supply
256GB SSD
144HZ Monitor

Could anyone be able to help me out with what is slowing down my performance during games?

I found this article for you that does a comparison test between both cards you have.

i5 6600k: 4 core/4 thread cpus are pretty limited in modern games...
8GB DDR4 2666MHZ: Single channel? Dual channel?
256GB SSD: That's not a lot of storage space... is it full? Is it free of viruses and malware?
^That.

OP doesn't mention having a GTX 1060. That's a typo of 1660Ti in their original post.
