Most functions are relatively easy on a processor so any reasonably new system will cope. The problem is the 1080p video. If you are just playing it with no transcoding on the fly fine, if not, you may have issues.
I’ve looked into the same many times and the issue is always around the movies files.
Transcoding is using a processor in real time (as your watching it) to change the 1080p into something the device your watching it on supports.
Basically if the only thing you watch films on plays the files in 1080p then no problem. If you want to watch on multiple devices then there could be problems.
