28" just doesn't have enough PPI (pixels per inch t create a clear picture.

The typical human eye can see individual pixels when PPI drops below about 96 ppi ... your monitor is beloe 80 which is why h pictire looks like a dollar bill "pen and ink" drawing.
When buying the best monitor you can afford, this is what I suggest
1920 x 1080, 144 Hz TN ($250) Opting for a better 1080p panel panel brings a cost increase that puts ya perty close to a 1440p screen. To drive it. start with the 1060 3 GB. G-Sync and Freesync don't come into play much here; there impact diminishes once ya get over 70 fps. Still there but not as great as it is from 30 - 60 w/ G-Sync (40 - 60 w/ Freesync.) At 70 fps, many folks will turn off G-Sync and use ULMB, Freesync does not have the hardware module that provides this feature tho. But you don't nee either if you choose a 120+ Hz monitor that can use Lightboost ... so here I recommend the Asus BG248QE which has been selling fo $250 for about 5 years now. See the list "Classic Light Boost Monitors" here:

2560 x 1440p, 165 Hz, G-syn / ULMB ($600+) . The price here is all over the place with the Predator XB271HU of late. I have seen it go from $299 - $699 up and down. This gets you and AU Optoncs IPS panel, w/ 10 bit color, Asus PG279Q uses almost the same panelw/ 8 bit color. The are some that cost more, some that costs less but that's the best panel I have seen as yet. As for anything in betwee, to my eyes .. ... what you pay for something less is just that ... less. You'll need a 1070 to drive it.
3840 x 2160 ... Nuthin. I have yet to see a panel that was worth the investment nor found any card capable of driving them consistent;y above 60 fps. And no 144hz at 4k till DP 1.4 monitors get here. A pair of 1080 Ti's will do it (50% scaling) but i think we are going to have to wait for the 1180 or whatever it's called. Investing in 4k roght now iwon't be a sound investment. The new 1000 nit HDR 144 Hz panels are ready to go and expected in Q2 2018 ... after originally being targeted at 1Q 2017. The AU Optonics panels are such a H U G E step forward that I expect the dollar value of everything sold up to that day will tank.
VRAM wise, we have no way of actually knowing how much RAM a game uses, utiliities only tell us what the install programs selects to be allocated ... if ya have more, it will allocate more. But a good rule of them is 1 GB per 500k to 700k pixels.
1080p => 3 - 5 GB
1440p => 5 - 7 GB
2160p =>12 - 17 GB
Or u still think 1080p is gonna be ok
