it lacks quicksync which helps significantly with respect to cpu consumption, its an old 2012 machine, its a power hog compared to a modern i5-6500/4590- particularly since you need to add graphics. No costs the same or more than the above mentioned alternatives...
Sure, but you are talking about reducing CPU cycles. I am at 30-35% now, not really concerning. The E5-1650 was sold all the way to 2014-2015, but did start in 2012. A used Nvidia 730 is $20-$30, but mine did come with a workstation graphics card that worked fine just didn't have an HDMI output like I wanted for my monitor. Now the power hog thing is probably right on. I should get a kill-a-watt and measure it. It is the standard power supply and cooling fans, so it is a bit louder.
I actually initially got it as a transcoding machine and server for Plex as it scores relatively high on the Passmark scale (11,800 when 2,000 is recommended for 1080p transcoding), but the installed Milestone and then finally purchased BI. For the price, it is working out great so far. I will report back on the cost to run the thing after I acquire a kill-a-watt meter.
