ASUS M4N78 SE with nForce 720a?

[MudkipMonkey]

Okay, so I'm thinking about upgrading my pc's processor, so I got into what motherboard I have, what Chipset, I have and What processor would fit in the socket I have.
So I got CPU-Z and it says my motherboard is ASUSTek M4N78, my chipset is NVIDIA nForce 720a and my soutbridge is NVIDIA nForce 720a MCP. But when I was gonna check for a possible BIOS update, the webpage of my motherboard says it has 'NVIDIA nForece 720D'?

Does anyone know if it even matters?
Or maybe CPU-Z doesn't know my motherboard..?

Edit: I thought maybe it was important to say I'm on BIOS version 0221

Oh thanks.
One more question:
According to ASUS my motherboard can use Phenom II processors, but according to that site it can't?
