The monitor is a 60hz 1080P IPS display with 6ms of lag. Not the best but it's not horrible either. Until this year 5ms of lag was standard for IPS. Your GPU is the weakest link. With everything except hair works at ultra and 1080P a GTX 1660 Ti would get you there. There regular GTX 1660 might as well but if you're upgrading going to the Ti, the RTX 2060 , or 2060 Super (essentially the old 2070) would be a good move for future proofing yourself a bit VS just playing games from a few years ago well. And for a quality of life improvement get a 1-2TB SSD For 100-200 dollars you'll have a massive quality of life improvement with loud times dramatically decreasing. On top of that in games you'll experience less pop in. The CPU is a bit dated now but it'll play the games you like and with Intel about to make a big improvement next year and AMD ready to launch 4th gen Ryzen (Zen 3, confusing right?) to compete. While the GPU's especially with the RTX 2060 Super for around 400 should be a solid card for years to come. 1660 is 200-225 with the other cards slotting in between those and just think of how much do you want to spend now VS years it'll be able to play modern games. Oh and if you're thinking about just grabbing a console I'd say go for XBox for gamepass unless there are a bunch of PS4 exclusives that you need. You get a few hundred games that you can download. And if you like FPS/Sports games both PS4 and XBox have EA access which is a similar thing with most EA games going on it 6-12 months after launch.
