im not close to it right now, between which machines are you?Press more info, and screenshot the info pane giving your Mac Pro identifier..
Looking at the ram speeds I would say 10.7, think its a 2,1 you have at most..
Yes the original is installed, but Its the graphics card that stalls it in running MavX or ML?That's a Mac Pro 1,1 (2006) model.
Officially the latest version that it will run is OSX 10.7 (Lion).
However with a more modern graphics card (assuming you haven't replaced the original graphics card) it can be made to run OSX 10.9 (Mavericks) by replacing the boot.efi.

boot.efi replacing is a software change or hardware?However with a more modern graphics card (assuming you haven't replaced the original graphics card) it can be made to run OSX 10.9 (Mavericks) by replacing the boot.efi.
Yes! It is. It's something about 32 Bit and Apple's change to 64 bit in their newer OS'es.
software only.boot.efi replacing is a software change or hardware?
The Maximum OS you can install is 10.7 "Lion".
I'm trying to think, but is Lion on the App store only? So I think your going to have to buy Snow Leopard>Then buy Lion. (Since Lion never came in a disk format to my knowledge) Someone else can confirm that.
You would have to call Apple for download code. They don't even have 10.8 for sale on AppStore to my knowledge. I have always had to call a salesperson for lower OS. Gotta love the 'new' PITA model. Quickly get crap software sure. Only have one AppleID, perfect. Anything else is a big bag o' Apple hurt.
They hide by default any previous OS X versions in the App Store. Choice out of:
Calling Apple
Create a new user account on 10.6.8 system, sign in with Apple ID in App Store and buy.
Or become 'Jolly Roger', install it disconnected from the web, then reconnect, sign into the App Store and buy.
You can find it in App Store? I looked everywhere. When I called Apple told me "Yeah we don't offer those in the App Store". Hmmmm.
Not in the App Store directly, but you can buy Lion and Mountain Lion from the Apple online store which gives you a code to redeem in the Mac App Store.
