Blue Iris hardware, is this a good deal?

Look at the 590-p0033w, i3-8100, on EBay. I purchased two of these recently for $215.00 and $230.00, auctions. Both are new. I have 5 cameras running, with low settings, and the cpu is running at about 18-20%.

I’m still playing with settings as this is a new computer I just purchased. This one is much less powerful than my previous one and it couldn’t keep up with the settings I had on the old computer. The camera settings I play with most are frame rate and bitrate. At the present time they are set at 8 and 2048. I have 6 cameras running 3 record continuously and 3 when triggered. My CPU usage fluctuates between 16 and 21%.
