What can I improve on my old setup? For a maximum of 200 euro
Ultradesk desk with RGB
I7 7700k
Asus RTX 2060 great
MSI z270
16gb Ram Hyperx Fury 3000mhz
500gb Samsung 970 Evo plus
Corsair Carbide 300R case with 6 fans and Be quit Dark 4 Pro
Ps4 and then I have an Acer monitor with 77hz
And a Hyper Cloud 2 headset and 4 Ps4 controllers and 3 Xbox controllers
And then I still have a 250k line
If you only have a monitor, you can upgrade here.
The same applies to the audio setup, which could be improved.
Leave it that way and save your money for another year and then look around the market in a year to see what you will get for a thousand, let's say
But only applies if you have games with which your current hardware is hopelessly overwhelmed
3600mhz Ram or 2nd monitor (more hz or better resolution)
Well I would be the first graphics card and processor, but they are way outside the price limit, so maybe a new monitor
I have I9 10900k and ne Rtx 3090 with my mother, but when I'm with my father I don't want to drag my PC with me
Since you haven't listed all the components of your setup, including keyboard, mouse and mousepad, I don't know if you would like any recommendations in this direction at all.
I read in a comment from you on another answer that this is your second setup. So I think it's unnecessary to upgrade the PC. Also due to the low inventory of hardware and its prices at the moment.
I would go towards the periphery with the 200 euro. You could build a custom keyboard, which you put together according to your personal preferences and then assemble it yourself. It would also be worth investing in a lightweight mouse, as it is much easier and more intuitive to move using the mouse pad. Instead of a mouse pad, you could also buy a large Deskmat, which also has space for a keyboard and mouse.
I hope my suggestions could give you some inspiration!
