I3 and i5 intel

Why recommended intel i3 over i5 just for graphics or something else?

Hey, Dimitris! I would go with the i5. Heck, I personally run an i7 based machine as my Roon Core. The extra processing horsepower comes in handy, especially if you are having Roon doing any transcoding on the fly, like DSD to PCM conversions, OR, if the server is handling multiple audio stream requests from various endpoint around the house. Also, why I have everything wired and only do Wireless for the tablet control point.
