I got a 1440p monitor so I can only game at 2k. After I got my 1440p monitor I could never go back now to gaming at 1080p resolution.
yea 1440P is the sweet spot, I've been running that for about 3 years now. I can never go back to 1080P either and 4K everything is too small for my liking.
regarding "AMD graphics card get faster with time due to drivers" same is true with Nvidia.
For the price point my 1070 has been great for 1440P @ 60fps and i got it over 6 months ago.
