Dual CPU MoBo

hello!

I'm in the process of researching for hardware to build out a VM Lab and was wondering if going with the Dual CPU route would make sense.

There will be about 10 VMs running simultaneously as such:

1 VM for Domain Controller

2 VMs for SharePoint 2010
2 VMs for SQL Server 2008 (testing clustered sql setup)

2 VMs for SharePoint 2007
2 VMs for SQL Server 2008

1 VM for running web services, etc...

I will probably be adding more VMs (running Oracle DB) as I'll be doing more development, testing and demos...


On each VM I will have Windows 2008 Server and Visual Studio 2010 installed.

On host I will run Windows 7 and using VMWare workstation or server.

For these VMs i will be RDPing from a laptop on the home network to use them..


Also, I would like to also do some gaming as well along with video editing... i'll be also doing web design using Flash, SilverLight and graphic design as well...photoshop, after effects....


So please let me know what is out there as far as the motherboards supporting dual CPUs... and I'd like to know if I could use dual Intel i7 procs?

I really don't know much about what's new nowadays in the hardware arena... so please provide me with your feedback... please let me know if dual CPUs is overkill for what I'm trying to accomplish...


thanks for reading and your feedback.
