RAM and VRAM.

add one more 8gb ram to be dual DDR mode for faster ram speed... one single ram is slowing down your pc................

 

How much memory is enough? What speed is needed? The answer to both depends on your monitor's resolution. A system that's perfectly adequate for running 1080p (1920x1080) at 60fps might be in way over it's head trying to run a monitor using Ultra 4K (3840x2160).

Something I learned long ago, back when memory was measured in megabytes instead of gigabytes, monitors were 19 to 21 inches, and gaming graphics were a lot simpler: Regardless of how much memory your video card has, always install the maximum system memory your motherboard will allow.

EDIT: And needless to say, a faster processor is always better than a slower one.

 

There's a hardware subforum somewhere.
The 8GB VRAM is OK for 2020. Even higher end cards like the 2080 have 8GB VRAM. It hold textures and assets. For games like CS:GO, it should be almost irrelevant, as the game runs on almost anything. Once a game eats the entire VRAM, it tends to "spill" on the system RAM, which is slower, and you want to avoid that. Very few games will eat so much VRAM though, although they exist. Turning up the resolution, using hidef texture packs, RTX will increase VRAM usage.
8GB RAM is getting a bit low for gaming in 2020. It should still be sufficient for casual gaming and esports. Single channel will eat into your performance. You can add another stick if you feel like it, or you can just exit browsers and the sort when playing games, use lower settings.

 

With the way the system handles ram, if you use close to the full 8gb, it will start to store memory in the page file on your hard drive and that will slow things down quite a lot.
That being said, from what I've heard, CS-GO only uses ~2gb so if you don't have 40 chrome tabs open, you should be fine. Generally the advice you've heard is correct. VRAM, Video card efficiency, SSD, those things generally affect gaming more than 8 more gigs of ram. The caveat is that if you do hit the ram limit you will have severe lag spikes from the hd usage.

 

Congratulations on your accomplishment of posting the most ridiculous thing I've read in quite a while. Everybody knows Nvidia is fps king right now so I don't know what your point is. AMD graphics cards have great value for midrange and lower cards. I'd be glad to show you my RX 470 I got for $70 on ebay that plays almost every game like CoD Warzone, Shadow of the Tomb Raider, and Battlefield 5 at 60fps at 1080p. Try getting an Nvidia card for that price that does that. I hold no allegiance to any corporation. I like whatever has value. If I had $1200 to spare I'd buy a 2080 ti, but I don't so I have to get what I can afford. The 1080 ti is no slouch either and is still a great card even though it's about 4 years old. But Nvidia has nothing in the midrange to compete with the price/performance ratio of the OP's RX 580. And you have to ask yourself why Nvidia will soon release a 3080 ti that if the reports are correct will draw 400 watts. The only reason they would release a card with such ridiculous power draw is because they're squeezing every last bit of performance from a turing refresh that they hope will keep them on top of the AMD RDNA2 cards that will be released in the last quarter of 2020. Right now in the cpu realm AMD is sh*tting all over Intel which is forcing Intel to add hyperthreading to their less expensive sku's and forcing them to lower their prices, and that's also the reason that Nvidia is a little worried right now. Competition brings prices down. Got it? Good.

 

When a game starts it reads parts of the game from the hard drive and writes those parts into ram.
So then you have your cpu with ram running the game but the screen is probably black at this point as data is moved to vram.
The game begins putting what it needs into vram and what it needs into ram and then the game starts.
The game swaps what it needs in and out of ram and vram from data to and from the hard drive or ssd.
So it's the game and operating system that handles putting the correct data in ram and vram as needed.

 

If I'm understanding you correctly and you want a chance of being one of the top esports players, for maximum frame rates you need a 2080 ti and i9 10900k. The 2080 ti is a lot faster than amd's top card, the 5700 xt. The i9 10900k is a little bit faster than amd in games that take advantage of higher clock speed.

I don't know what esports games are amd optimized, but in a gaming competition, wouldn't you want the fastest possible hardware? An amd optimized game is still going to get higher framerates with a 2080 ti.

 

DOTA 2 has set the tone for esports these past 10 years for example.
And it had for a very long time both Linux and Vulkan support (Valve has played a large part in making Vulkan what it is today)
Since Nvidia could not cheat on this title, the results of similarly spec Nvidia and AMD have always been close.
But for other titles, it's no secret that AMD is handicapped via backstabbing bribing shaddy deals Nvidia is (still) doing with game developers.
And let's talk about the elephant in the room when talking esports: you don't care about max frames, you don't care about min frames, what you care about is microstutters!
These have plagued Nvidia way more, with bug reports being ignored for literally years!

As for vram vs ram... there is no contest when it comes to gaming.
The GPU can and will load and unpack/decode huge textures directly in VRAM, without going back and forth to system RAM or HDD.
vram is optimized for throughput (256GB/s vs 25GB/s for DDR4 RAM - and in OP's case, just half that due to single channel),
vram is bi-directional (while RAM can only write or only read at one time), and what it loses in latency, gains by addressing more areas at the same time.
System RAM can only be better when the GPU is a cheap lame for office with huge latency 64bit VRAM, no matter the amount of GB's. RX 580 is a monster.

So, you are fine with 8GB of RAM. You don't have to match or have twice the size of your GPU VRAM, just like you don't have to do that with HDD capacity.
But it would make it so much better to have two sticks of RAM. It practically screams for dual channel to the point of even exchange it with 2 x 4GB (that would lower the resell value).
And is worth considering that WWW, windows, games, programs all expect at least 16GB RAM - no developer bothers testing on a machine with less than that.

 

1. Please add a note saying that VRAM is Video RAM, not Virtual RAM.

2. More important than how much RAM you have is the configuration of that memory. If 8 GB is all you can afford, you will get better performance with 2 sticks of 4 GB each. Strongly urge you to get another stick of 8 GB of the same type and speed, preferably same manufacturer, or just get two sticks of 8 GB (they need to be identical). Then you'll have 16 GB RAM, which is good, but the real benefit is that it is 2x4GB.

3. The optimisation of games you talk of was significant several decades ago. Now the difference is practically negligible, unless you're a gaming nut for whom every FPS matters.

4. If you don't already have an SSD, GET ONE. This is a no brainer - the apparent performance boost is staggering as compared to an HDD.

EDIT: check the manual of your motherboard - here are a few out there that need THREE sticks of matched RAM.

 

most boards have 4 ram slots, so you can install 128gb
there is no point in that
32 is more then enough and 16 will do the job also
