i7-4770 or i7-4790? Those Haswell-based CPUs are legendary, even in 2025. I built an i7-4790K based gaming rig probably 10 years ago or so, it was an absolute monster.
For VMs on Linux, I would recommend something called "Virtual Machine Manager". It's in nearly every distro's software repository, and uses qemu (common virtualization tool in Linux servers all over the world) for the backend. But whatever you do, stay away from "VirtualBox".
