X1800 used for server, not doing much

[4Qman]

I have an x1800 Itachi motherboard with 32gb ram.

I user this server for unraid, 90% of the time it's used to host nextcloud and maybe 2 or 3 Plex streams at most. I may run 1 or two VMs later down the line (6 cores each)

I'm sure if it's worth upgrading/downgrading to a newer CPU for power efficiency.

Probably not, with power saving enabled similar generation CPU's usually consume very similar amounts of power at idle and CPU's are usually ~5-10W idle with the rest going to board, memory, GPU, drives, PSU losses etc. Anything you spend is unlikely to pay for itself any time soon.

1W is ~ £2.60 / yr so a 10W saving nets ~ £100 over 4 years.

I'm still running an E5-2660V3 (10C 20T) as the cost of a platform change would kill any saving over the next 5 or so years.
With 10 drives spun down, and a Quadro P2000 for transcoding, it averages 70W idle.

You should only upgrade if you have performance problems or you need some newer cpu tech. Money saving are not a real thing when talking into account platform upgrade costs.
