    4k Monitor

    I have a gaming rig and I’m looking to upgrade my monitor to something in the 4k variety. I’m not sure which route to take. I’m looking at the new Asus monitors that are coming out. The Asus PG279Q and the Asus PG27AQ. Both are IPS and support G-Sync. The PG279Q has a resolution of 2560x1440 and a refresh rate of 144Hz. The PG27AQ has a resolution of 3840x2160 but a refresh rate of only 60Hz.

    My current system has a Core I7 3820 on an Asus Sabertooth x79, 32GB of Corsair Vengeance DDR3 RAM, an Nvidia Geforce 980GTX, and an Asus VG236H 1080p monitor with a refresh rate of 120Hz.

    First off, do I have enough under the hood to run both or either of these 4k monitors in a gaming situation? I play all sorts of games from FPS to MMO’s. What kind of effect will the different refresh rates make as far as gaming experience? Finally, if I upgrade to the monitor with the lower resolution, will I notice much of a difference (graphically) from my current 1080p monitor? I’d appreciate any advice or suggestions you can give.

    First, only the 3840x2160 monitor here is 4K - marketing-wise at least. 1440p isn't 4K.

    That said, on your current rig I'd be getting the 279Q. A 980 by itself doesn't really have enough balls to push 4K fluidly. You'll get roughly 15 FPS at high settings. Fine for RTS but way too slow for anything with action in it.

    However, you're stepping up from a 23 inch 1080p panel which is already pretty tight pixel-pitch wise. So you'll gain real estate, not necessarily sharpness. That said, the jump into adaptive sync is well worth the price of entry. I have the FreeSync (AMD) version of the 279 and it's beautiful. You only need enough horsepower to maintain 45FPS for fluid game play (the lowest end of the adaptive range). I'm not sure what that value is for the G-Sync one, sorry.

    Definitely do the panel upgrade, but skip 4K for now ☺

    Hello shaithes

    Going from 1920 x 1080 to 2560 x 1440 you'd see double the picture quality. Being that both monitors you're looking at have IPS panels they will have better color accuracy over your current monitor which has a TN panel, so that will also improve picture quality.

    Going from 2560 x1440 to 3840 x 2160 will double the picture quality once more so going from 1920 x 1080 to 3840 x 2160 will be four times the picture quality.

    A GTX 980 will suffice with pg279q but you probably won't hit 144 frames per second in most games but as long as you're hitting 60FPS or above you will have smooth game play.

    One GTX 980 isn't enough horsepower for the pg27aq, you'd need at least two or even three gtx 980's to hit 60FPS in most games and with the GTX 980's 4GB of Vram it's really not enough, so while the GTX 980 is still a good performer it isn't up to standards for 4k gaming.

    My recommendation would be to add another gtx 980 for the pg279q to get you up around 144FPS.

    If you go with the pg27aq, then you will need a gpu upgrade of at least two 980ti's or two titan x's, if you can afford three then all the better.

    The main difference between a 60Hz monitor and a 144Hz monitor is with a 144Hz monitor you will get no motion blur with higher frames per second.

    A 4k monitor and the hardware to run all games at 60FPS is a dream machine. As of right now all 4k monitors are 60Hz and is due to the limitation of displayport 1.2
