Question about GPU upgrades

[Subratrix]

I currently have the Radeon Sapphire Nitro+ RX 480 8GB GPU. It still runs very well and I am using all of the ports on it for 4 monitors. I shouldn't need to upgrade for another year or two, but I'm not sure what to start looking for in a new GPU. This card starts to struggle with more than 2 videos playing, granted there are 4 monitors going. All games run smooth and at a decent FPS. Any suggestions or tips as to what I should be looking for in a new GPU? I still want to run 4 monitors. I usually have 2-3 instances of Minecraft running (I am an admin on a server and have 2 accounts on it, plus one more on my personal server). One monitor us usually dedicated to Discord, 2 usually have Minecraft on them, and the other is for videos.
EDIT: Forgot to mention my monitors.
Main display: Asus Acer Gaming Monitor 27” Curved ED273
Secondary display: Samsung 24" 1080p monitor
Third display: Sceptre 24" tv
Fourth display: Hisense 4k 43" tv

Any help or advice is greatly appreciated! Thank you.

you could grab another low end card like the rx 550 for the extra videos you're running, all nvidia gpu max at 4 monitors and all amd max at 5, but you can continue to use your 480 if you plan to switch to a more powerful gpu.

also a dumb suggestion, but you could grab a titan for all that sweet sweet vram you're bottle necking on, but multi gpu works better in most situations, especially if you can get virtual machines to work

I'm not fully aware of what vram is or what you mean by virtual machines. I've built my PC so far and still learning new things from LTT every time I watch his videos haha. And which titan would you suggest? Aren't there a few options for them?

Definitely don't need a titan or more vram. I am surprised a RX 480 is struggling to display more than a few videos at once. I highly doubt is a vram amount issue.

 

@Subratrixvram is video card RAM, so your GPU has 8 GB of VRAM which is a plenty respectable amount. For instance, I run games at 3440x1440 and even with that, most of my games don't use more than 6 GB of vram...

 

I would be curious to see what the streams are that are struggling, are they 4k amazon/netflix streams, or 1080p youtube? That very much matters. 

 

Also, why go with a 9900k as your next upgrade? Minecraft is not the most intense thing to run, but why not go with a Ryzen chip? 9900k is 100% the best "max FPS possible" chip, but your paying a lot of money for a few % gain in FPS over a 9700k or a Ryzen 3700x. And on the multitasking front, a 3700x would be a better option. Just a suggestions.

There's only one option for titan at this time, the titan rtx. The only reason I'm assuming your bottle necking on vram is because of the minecraft instances, the higher your graphical settings, the more vram you use. I find that at 1440p at 32 chunks I'm at 40% vram usage on java. That said the titan is still a very dumb purchase which will be explained when I go over virtual machines.

A virtual machine is an instance of an operating system running on top of another operating system, sort of like an application. You essentially split up your system resources on a master operating system, and then have a slave operating system run on top. Often issues with virtual machines is that you need server grade graphics cards(nvidia quadro) to split its resources between the instances, so most people just opt for the much much much cheaper multi consumer level cards set up. You can grab 47 $150 gpu for the same price of a quadro p6000, also known as the binned 2080 ti with a different driver.

So yeah my recommendation is buy the amd ryzen 9 3950x and 3 more rx 480 and splitting then up into virtual machines for your tasks. And also do a bit more research than what some random guy on the internet was able to scrounge about on google over a 10 minute period.
