I mean everything except the cpu looks fine, but don't expect any magic.

Honestly, having a great monitor is going to make GTA V look better than changing from 1080p to 1440p. Lower resolution on a bigger screen always looks grainy, but in the settings you can adjust resolution multiplier so it'll look even better and you can customize it between 1080p and 4k if you really wanted to. Since CPUs have very little impact on FPS, I wouldn't worry about it. The difference between your 6 year old CPU and a brand new one is 10% performance on the average game. 1070 is a good card, it should run 1440p no problem. But remember, GTA V is not coded very well, so mods and plugins are going to drain the games resources lowering it's FPS
