Woo hoo! Congratulations. Any improvement is great, don’t let naysayers tell you anything. In the end it’s about being able to play the games you want to (I spend the equivalent of €1500 on my PC and play minecraft 😂)
You can always make incremental upgrades… first limit you will probably encounter is RAM which you can change to either 8GBx2 (better) or 4GBx4 (Not as good but cheaper since you just add 2 modules).
When you have the financial ability to do a full upgrade in a few years, then you will get several generations ahead. !patientgamers will be your friend. And if you need more games but have no €, make sure to get the Epic freebies when good games are released there.
