will this rig can do 10 vm''s , need some opinions

idk how, i have the same setup and 4 is just my maximum (and still epic fps drops )
you use windows 7? Did you using some solutions to make vm\poe\eb work better?

 

Make sure your virtualiation is turned on "enabled" on your mother board (bios settings). Sometimes the name doesn't even have "virtual" in it, its vander pool, or something like that. Also I assume these guys are running there machines overclocked, which is a huge advantage. I have a i7 3770k cpu, and reading all these guys with welfare cpu's running just as much as i was got me thinking. So I rechecked my whole system, and it turns out my cpu wasn't even overclocked, nor did it have that virtual setting turned on. My must have reset it to default when I got my computer again

 

I'm using win10 pro, does win7 use less cpu resource?

 

Use lite os of either win7 or win8-10, with unneeded features turned off

 

How do you turn off unnessary features and which ones?

 

You don`t have to, look for OS that already has them disabled.
