I have recently bought a new 1440p 144Hz monitor but I can not achieve even 100 fps on some games. I looked at the usage and tried different setting like dropping to 1080p but no improvement. Battlefield 5 is the game I play the most right now and I am looking to get into Metro Exodus but I want to upgrade my cpu. I currently have an i7-3820 @ 4.75GHz and I hit 65-80 fps. I would like to stay on X79 mainly because I can not afford to upgrade my motherboard, ram and cpu. I am willing to go into server cpus but I want to hit at least 120 fps and I am willing to OC. I have been looking at 3930k mainly and would that be enough?
