Consider using VMS or high-core systems when you need more processing power for Unraid. For your NAS, a 4-core setup works but can cause buffering issues, so a single PC with more cores is better. You mentioned upgrading to a 3900X with 12 cores, then allocating cores for Unraid and VMs, plus extra for video. Your plan includes one 5-core VM, two gaming cards, and two additional VMs. The onboard card and two gaming cards are your current thoughts. For a single gaming rig, you’d likely need a powerful CPU, and for dual gaming, even more. Keep in mind the cost and performance trade-offs.
