Hmm. General concepts for hardware:

For gaming the relationship of the cpu, gpu and monitor can matter.  Generally for games at least the cpu builds the frames, the gpu draws them, and the monitor displays them. All will have a maximum rate, and the number of fps the cpu and gpu can push out varies by game.  The monitor has a flat max of how many fps it can do regardless of game though. If you can run 170 fps but only display 60 extra speed is just wasted. The monitor controls the maximum useful frame rate because it has the end of the chain. A small slow monitor means only a certain level of cpu is useful for games and an even slower gpu can be used.  The PSU will vary according to the power draw of the gpu and cpu together.

 

 PSUs can be dangerous if you open them up, and will always eventually fail.  How they fail and how long they can go before before failing is the primary driver of PSU quality.  80+ rating and presence of RGB and modularity play no role in that.  
 

Memory size is generally the least important for gaming.  You can often get away with 8gb, barely, but if you’ve got an apu/iGPU, it will need motherboard memory too so the effective number shrinks. Most people run 16gb for gaming.  Sometimes 32gb.  Simply because if you want 32gb later it might not be so available. 
Memory speed is limited by both the MoBo and the cpu.  Slowest one is the effective maximum.

 

Theres more of course.  Cooling comes to mind.  You need enough of that so that neither the cpu nor gpu overheats.

So my CPU is AMD Ryzen 5 3400G with Radeon Vega graphics, and how do i decide what GPU i can buy?

Would need to know more about the system.  Memory and to some extent motherboard would say how fast the cpu could be.  
 

I can tell you what I’ve been told about the 3400g.  

3400g is an apu.  It’s got a graphics card in it that will do 2d fine.  3d and gaming usable for many of last year’s games, not so usable fo next years games. it’s an older cpu type. A 3400g is a ryzen+ (Not ryzen2) 4/8 gpu with an integral vega gpu that uses system memory.  It’s more powerful than my old 4770k even with its low overclock, but not a lot.  My machine is pushing obsolete pretty hard. I run a 580 in my machine and it’s about as much graphics card as it can usefully use. Might be able to handle 2k with enough graphics card. So 1080p@120 or 1440p@60. Depending on the game.  Won’t hit 1080p@60 in everything out now.  May have issues with win11.  I don’t know.
