This PC has 8GB of RAM and so it is possible to allocate 4GB to VirtualBox and still have enough to run Windows. This means that a 32-bit OS might run a bit faster because this setting can be off. This slows down the virtual machine very slightly, but it is essential for running 64-bit guest operating systems like Windows and Linux.
