Recently got my hands on a Rog Strix 4090oc and am ready to upgrade my motherboard cpu and memory. Looking like the Ryzen 7950x3d with ASUS or Msi X670E but not sure on what Ram speeds would be best for this combination? I Mainly play ACC on Triple 2560x1440p monitors. Also a friend suggest waiting on the 7800x3d over the 7950x3d? This sound right?
