Which is the best value GPU to run a 1440p, 144Hz and a secondary 1080p? Also is it better to have the secondary screen running at 144Hz or 60Hz? I use the main screen for gaming and the secondary for browser, music, etc. The rest of my build is already good (i7 4790k, 16GB RAM, etc.).
Since I'm here I wanted also to know more opinions about these monitors:
MG278Q, PG278QR and S2716DG. I find the first one is the most value for its price, but I don't really know how much is G-Sync important and how it compares to FreeSync.
As a secondary screen i could use a simple 1080p, 1ms, 60Hz or my VG248QE.
