I'm currently running a stock i5- 6600k, without the capability to OC due to the motherboard, and a RX 480 8gb. I just bought my first 1080p 144hz monitor, upgrading from a 60hz, and want to be able to play games as close to 144 fps to utilize the new monitor. I mainly play Black Desert Online and notice my GPU utilization is always at 100% while CPU varies from 50%-80%. I also occasionally play Call of Duty Modern Warfare with a solid 60 fps on very high settings. Would upgrading the GPU to a 5700 xt be a waste for my use case or should I upgrade my mobo and CPU first?
