Is bottlenecking bad for my PC?

No. Bottlenecks don't damage hardware. They simply prevent you from achieving maximum performance.

How do I know if my PC has a bottleneck?

Monitor CPU and GPU usage while gaming. If CPU is at 95-100% and GPU is below 90%, you have a CPU bottleneck.

Should I upgrade my CPU or GPU first?

Upgrade whichever is the bottleneck. Use our calculator to identify the weak link.

Is bottlenecking more noticeable at 1080p or 4K?

1080p shows CPU bottlenecks more. 4K shifts load to GPU, masking CPU limitations but exposing GPU bottlenecks.
