I'm thinking of upgrading my GPU and CPU. I'm only able to get around 30FPS in Metal Gear Solid 5 on default settings with my HD 7850 and AMD Phenom II X4 965 BE, which is prompting me to make some upgrades. I'm not sure if I'm willing to get both a new CPU and GPU right now, so which of the two components do you think would be better to upgrade to get better performance for games?
