Want to upgrade Sony Vaio motherboard

Hi. I have a Sony Vaio computer that uses the Asus motherboard. I'm interested in upgrading it with a new motherboard capable of supporting one of the high-end processors such as the AMD 5600. Below is the info on this machine and the existing motherboard.

Can you tell me if I can replace the current motherboard with the new Vista-ready motherboards? If so, is there any particular model or will any of them work?

Thanks in advance,
