open box bought
I built the above which plays GTA V at 1280x1024 @ 60 Hz (locked, 0 frame drops) (note I had to sacrifice shadows to "high" not "very high", FXXA)
The cost was under $500 n.i. Windows 10 purchase, because I took advantage of "open box" retail deal on mobo and video card and case.
I'm unsure what Destiny 2 requruires but first thing i'd upgrade on my build is "1050" and make that a ? 1080?
Anyway the Destiny 2 site should have "minimum requirements" and "suggested requirements", and i think to pull solid 60 fps without frame drops you'll go with suggested requirements and a little nicer video card than they suggested in the suggested requirements, one model up from that.
From my build (which may not be right for Destiny 2 ) that would be ~ $700-$800 build.
