Looking to upgrade existing gaming system built ~2 years ago

Approximate Purchase Date: Likely this month. Once I start looking at stuff I get pretty anxious to get it done.

Budget Range: No real budget. Currently thinking I bump up to the next tier of graphics card which will run me around $400. Open to other upgrades, but not looking to rebuild the whole system.

System Usage from Most to Least Important: Gaming, basic internet browing.

Are you buying a monitor: Probably not.

Parts to Upgrade: Video card, others possible if recommended

Do you need to buy OS: No

Preferred Website(s) for Parts: No real preference, though I am most comfortable with newegg or amazon since I have purchased most of my parts from there. Other stuff I picked up from Fry's or Best Buy in store.

Location: San Diego, CA

Parts Preferences: No real preference

Overclocking: No

SLI or Crossfire: No

Your Monitor Resolution: Current monitors are 1920x1080

Additional Comments: Currently mostly play Overwatch, but I have played a range of games on this build (Fallout 4, Witcher 3, GW2, ESO, BDO, BF1)

And Most Importantly, Why Are You Upgrading: I get some graphics glitches that can be annoying. Had some issues with BF1 crashes (possibly issues with the game itself more than the system). Issues are usually one of 2 things:

- Flickering square on the screen (roughly 2"x2"). Happens on both monitors. This one doesn't really affect much and I can play through it until it goes away.

- The real annoying one is harder for me to describe. Basically it is like you grabbed a pixel from an image and stretched it across the screen. If I look my character in another direction it goes away, but comes back if I rotate back. Varying degress of this that range from annoying to making a game unplayable until I restart the game. Stays with the game even if I move it from one monitor to the other. Some form of this has happened in every game I have played on this system at some point. It feels like this happens frequently, but in reality it probably only happens every couple of days.

Overall, I have been very happy with how my system has performed otherwise.

This is my existing build

I am definitely open to any good value upgrades that would be simple to execute. At what point would I need to add more cooling to the system? There seems to be plenty of room left in my case if I do need to add anything.
