Thank you for all your helpful answers.
I've already made a few changes to the game's graphics settings, and I've also changed the renders with "Reshade", which gives me more realism and less shine without any loss of FPS.
Budget-wise, it's pretty open-ended. My previous PC from 2015 cost me 1,100 EUR at the time and it lasted 8 years without a hitch, thanks to a CPU upgrade 4 years ago.
Now, with the change of graphics engine and the massive battles in WvW, I can see the limits (I hardly exceed 10/15 FPS, unless I set all the graphics parameters to low, and then the game gets hideous).
So my budget would be between 1,700 and 2,700 EUR, I know it's a lot, but I figure that with a PC at 2,700 EUR I should be able to play all future games at maximum graphics. Maybe even play Guildwars 3, who knows 😉
So far in the budget: I'm going with this :
High: For 2700 EUR: i9-14900K/RTX 4060/32Gb Ram/4To SDD
Mid: For 2200 EUR: i7-14700KF/RTX 4060/32Gb Ram/2To
Low: For 2000 EUR: i5-14600KF/RTX 3060/32Gb/2To
I'm sure I'll be fine for the 2,700 EUR one 😄 But will the Low and Mid setups give the same results?
