Windows 7 x64 Question

I think my installation is correct, but ... here is my confusion ...

1. I have seen screenshots of the virtual machine library where it lists "Windows 7 x64"
2. I read a post (VMFusion 3.x that talked about setting the VM Type to x64).  I dont think that option exists in VM5.
3. My virtual machine library initially said "Windows 7".
4. I definitely have the 64 bit version of Windows 7 installed as it says so under Control Panel > System

My guess is that this is just a naming issue (I've already changed mine to Windows 7 x64).  Why it initialy listed it as Windows 7 may be because

1. I installed from a x64 only DVD, rather then an x86/x64 DVD
2. VM Fusion never names it Windows 7 x64.  That is done by users only.
