Yea, due to the lack of helpful answers, imma make a quick build for you too;
this is based on the German market (since I know the shops here and because pcpartpicker doesn't have a Croatia for whatever reason)
For 800€ you can get a full "low budget" current-gen pc
https://de.pcpartpicker.com/list/fMsNv3 for example (like ofc you're gonna have to look what sellers locally have, but for a general idea)
The i3-12100f is the current budget King of cpus, finally replacing the 3300x (if those even existed)/10100f
And for the gpu I just went for the cheapest rx6600/ rtx 3060 i could find (i should note technically the 3050 or even the 6500 xt are options, but since both are slower than even the 2060, I'd avoid them if possible budget wise).
The power supply is also on the low end, but I don't believe in overspending on a higher-end one with the hopes of needing it in the future when you're on such a low budget.
And the rest is just standard stuff with the case being a cheap af 50€ thing cause it at least cools the pc. If they already have old pc parts use them here!
Now you'll notice that my recommendation is spending a lot more on gpu than cpu despite, as Azzlack correctly noted above, Valorant being a cpu intensive game. The reason for that is that based on my experience, the 12100f can handle 1080p 120fps Valorant without any problems (with the 1% lows being at ~130 on my friends system), so you might as well get a proper gpu for other games.
