ill throw in my two cents on this, Dont do it, unless its life or death. If you have cash to spend you and time, and you need graphics performance, you can look into PCI passthrough (this is where you pass through your GPU to a virtual machine giving you near "native" performance) theres also CPU pinning but i can feel your eyes glazing over so i wont go into too much detail,
i understand youre a newbie but there are great tutorials you can blindly follow and come out ok, and you'll hopefully pick up a thing or two in the process.
In short, dont dualboot, if you have to, get a windows 10 LTSC and run it as a VM with PCI passthrough if you need graphics performance
