If you use Linux with full GUI's and default applications installed then they can be almost as resource intensive as Windows -- the best distros allow you to install the bare minimum functional system and then you can install a desktop GUI and select your own packages. Ubuntu for example installs by default a full GNOME desktop with zillions of packages that I don't know what they are and I'd never use --even things like libre-office etc.
If you have a 32 bit computer and can find a version of vbox that runs on it you CAN contrary to beliefs run a 32 bit OS on it even if the CPU doesn't have the vt-x virtualisation technology (or equivalent AMD setting).
You can't though run any 64 bit VM's on it.
If it DOES have vt-x you can actually run a 64 bit VM on a 32 bit host provided the CPU is 64 bit capable however remember HOST and GUEST together can only use 4GB RAM so experience won't be good !!!.
Current VM systems need 64 bit machines just to install the Virtual software system on it before installing guests.
But : Who uses computers with only 4GB RAM these days -- even a cheap mobile phone has more !!!
