So I have a 1080p monitor, so when i look into games im interested in, i go and see how my specs perform at that resolution. When I was looking at Marvel’s Spider Man, the reviewer said that the game was CPU bound at 1080p. I assumed this to mean that the GPU won’t be utilized much, however when I eventually bought the game, I had a consistent 80+% GPU utilization. What exactly does being CPU bound mean then?

“CPU bound” means that the game is limited in getting more frames by the CPU instead of the GPU. It doesn’t mean the GPU isn’t being used, but rather that the GPU being faster wouldn’t increase the FPS.
Think about what it means for the GPU to be at 80% utilization. Why not 100%? Both the CPU and the GPU are being used to produce the frames delivered to the screen and one of them will be the limiting factor. When your GPU is at 80% your CPU is at 100%, at least on one processing core.
