32 Gig Ram, AMD 3950 with a 2080ti, and I have run 15 on live with full effects with zero issues. While that is going I have been known to pull off a full game or world of warships or WoW with no real performance issues. Any good multicore cpu in the last couple of years, and you are going to be fine. EQ does not tax a modern graphics card at all, even at 4k res. cpu = Memory > Video Card. If your cpu is older, go with more memory. Any Iris powered Intel CPU will do fine for 6 as well.
