Is it time for me to upgrade my GPU?

Title: Is it time for me to upgrade my GPU?

Currently I am using a EVGA GTX 680 OC 2 Gig, I'm was hoping that I could get a better card with only spending around 350-450 beans. I'm looking to run games like Ark around 45 -60fps or black Ops 3 on High settings at 1920X1080 and get 45-60fps as well. Any help would be great.

From Nvidia, the GTX 970, or Gigabyte GTX 980 that is $460 on newegg, But since EVGA has the step up plan so that's another brand option for you to upgrade to the new Nvidia Pascal gpu line that might come out by late May early June.

From AMD 390 or 390x, or even Fury Nano for like $480( note Fury has frame pacing issues when vram buffer is saturated)

You can absolutely hits those marks with cards from AMD or Nvidia within your budget right now. A GTX 970, or R9 390 (maybe even a 390x) would do you nicely. However, both companies have their next gen cards releasing in the "fairly" near future. Pascal from Nvida and Polaris from AMD should boast much better power efficiency due to the move to 14/16nm FinFET architecture while providing a more than modest performance gain (i.e. no more "rebadging", etc). Couple that with some fancy new memory tech built in and the next gen of gpu's are looking pretty sweet. So I'd say yup, it's time to upgrade. But if you don't mind waiting a few more months, I'd really recommend putting the $$ aside now and hold off until new cards come out before pulling the trigger.

Btw, what psu and cpu are you running?

Awesome advice , thank you so much for taking the time to answer my question. I think I'm going to hold off right now.
