Regarding storage; I'll be running 2 SSDs in the cache pool, but thinking dedicating 1 to the VM like you mentioned.
Also, I was considering a Xeon E5 2620, because I read that more cores would be beneficial, but I'm scared it will cut into my game performance, since it doesn't have that strong of a single core performance.
But a chip like the I7-5820 would be enough considering my needs?
Lastly, when assigning cores to the VM, can I assign 4 of the 6 cores to the windows VM and leave 2 for unraid to transcode / memory manage etc?
And when the transcoding of the streams hits 100% CPU on those 2 cores, will it pool more power from the other 4 cores reserved for windows, or does unraid just max out the 2 cores and leave the rest of the cpu alone?
