I found that with a 16GB GPU the game can use over 12GB VRAM and only ~10-12GB RAM at 3440x1440 ultra which with what the system uses can put it close to needing more than 16GB unless you keep your OS tidy.Unless you're running a game that specifically calls for more (e.g., FS2020)
All of the above should be fine but check the model vs the MB QVL as I have seen a number of complaints about Corsair compatibility lately.Corsair ddr4-3200 C16 8 x 4 (32 gb total)
Corsair ddr4-3000 C15 16 x 4 (64 gb total)
Corsair ddr4-3000 C15 8 x 4 (32 gb total)
What do you guys think will work well with Ryzen 4?
