Virtual Machine Questions

Hey everyone, i'm fairly new to this whole scene

and was just wondering. how much power your computer needs to run 6 or more virtual machines at once?

I have a:
quad core i-5 2.25 ghz
8 gb of ram
1 tb of hard drive
and a radeon 6900 series graphic card

For 6, I would recommend you to get 16GB of Ram, your processor should be enough.
The hard drive is also enough (25GB / VM)

You don't need much to only run the vms but im guessing you want to open up ref bots. For that from my experience the most importatn things are ssd, cpu and ram. Without ssd the most you can run prob will be 6
