A new PC will have no problem to run EQ with highest solution possible. The question is more you won't have all of this lightshow active.
The game is 17 years old and no challenge for the video card, even SoE /DB upgraded the grafic a bit over the years
So let us know if you are back in the game Karve, we have a Social membership to keep the contact to our old members.
