With 8Gb of RAM I have been happily using Qubes 4 in my work workstation since rc2. I suggest to use the mirage firewall image [1] to save aound a Gb of RAM
The fedora 27 images can easily reach 5Gb of use under heavy load, but in gneneral I have pretty good performances and I usually have a couple of throwaway VMs and the main work VM running and dealing with web, co pilations of various sort and editing.
