The table tool lists the monitors based on their name, unless you change it yourself.
Usually at the end of the reviews they compare the monitor to other similiar monitors and they had this to say:
"The ASUS ROG Strix XG279Q and the ASUS TUF VG27AQ are two very similar-performing monitors. The XG279Q has a slightly higher max refresh rate, it gets brighter, displays a wide color gamut for HDR, and has a quicker response time. However, the VG27AQ has lower input lag, the BFI feature can flicker at a lower frequency, and it has much better ergonomics."
And here's a direct comparision.

The differences are rather miniscule, so you can pick the cheaper one.

That depends on how sensitive you are to ghosting. Also new IPS panels are faster than the VA panels, only exception being Samsung G7.
Take a look at this table tool. You can add more filters from the add column button.

You can also see if any monitor from these articles catch your eye.

And lastly, you should read the sticky as it has lots of good information that will help you make the right choise.
 

Well that is based on the monitor, and ips can have some serious backlight bleed, but look for one with reviews that don't mention high ghosting, and you'll be set, otherwise IPS is second and tn third

Hey guys,
 
I'd like to start this discussion to figure out the best and top gaming related mechanical, opto-mechanical or new technology integrated keyboards for 2020. I also now have the flexibility to upgrade from the probably 14$ keyboard I currently own and never upgraded to save on money because it works. Give me all of your suggestions with factual evidence that supports these keyboards to be the top contenders.  :))

A 240 should cool almost anything fine, Gamers Nexus's, and Optimum Tech's CPU test benches use 240mm AIO's and so it would likely be more than fine for daily use.

In the front, yes.

To get an opinion on the RAM speed, you might want to post the RAM speed. Are you using an SSD? What SSD?
 
I don't know what you mean by "open blowback". A blower aka typical reference cooler?
 
You of course can't just assume something should be fine based on the design or manufacturers' claims. You need to check your temperatures, make sure nothing is thermal throttling.
 
Is everything up to date? Your Windows looks to be a bit behind. How about GPU drivers? When's the last time you rebooted your system (actual reboot, shutdown these days only hibernates the system, see up time to confirm)?
 
How are you comparing yourself to streamers? Are they showing an FPS counter, and are they talking about the settings they run? How sure are you that they're also running 144Hz? Are you trying to stream yourself? Some streamers use a second PC to handle the stream, so their game doesn't take a performance hit.
 
Are you doing running anything else in the background while you're playing? Watching a 1080p stream (even if it's 60Hz, does any platform even support over 60 yet?) can take a surprising toll.

You only really need to worry about Windows and GPU drivers. Running any sort of automatic updater in the background is just going to consume resources for very little benefit. Generally most programs will tell you at launch if they want to update (let them), so you'll only need to go around updating stuff manually when you troubleshoot something (Windows and GPU drivers in this case).
 
My approach to stuff like BIOS and motherboard updates is: if it works, don't touch it. You can use synthetic benchmarks to see if your system is hitting expected numbers (Geekbench is a decent low-hassle option).
 
I doubt they're playing in 144Hz, they may not even be playing in 1080p (I don't know if 720p is still regarded as twitch's "sweetspot"). Do not underestimate the differences between refresh rates and/or resolution. Having a 144Hz monitor doesn't mean they play in 144Hz.
