My general thought for x86 vs. x64 depends on memory. If there's 3+GB, then I go with x64. If it's less than 3, I go with x86.

So, if I want to create a Windows 7 VM for use with Fusion on a Mac, should I create a 32 or 64 bit VM? I don't plan on giving the VM anywhere close to 4 GB of ram, so what other factors come into play? Does the host utilize more resources to run a 32 bit system Vs a 64 bit or vice versa? Thanks, --Al
