Specs:
This is a pre-built Asus G11CD got it because it was selling for $1100
CPU: i7 6700
GPU: GTX 1080
RAM: 16 GB DDR4 2133 MHZ
PSU: 500W
512 GB SSD
2 TB HDD
Monitor: 1920 x 1080 144HZ
So basically whenever I play games the GPU never stays at 90-100% usage and in some games, such as Overwatch (epic preset 100% res scale) it drops to 70% (FPS varies from 120 to 210 in game). As for my CPU it hovers around 64% when playing Overwatch with none of my cores being maxed out (some are close tho). Temps are fine with the GPU at 82C and CPU at 65C. So my question is what is bottlenecking my GPU, only things I can think of is the CPU or the PSU, want your guys' opinion. (As a side note, I tested the Division (ultra preset) using in game benchmark and avg GPU was 95% while avg CPU was 65% which resulted of an avg fps of 90)
