1 CPU vs 2CPU in Hyper-V

Hi,
 
 I am debating whether I should get 2nd CPU for HP ProLiant ML350 Gen9 Server with 1 x Xeon E5-2620V4 / 2.1 GHz 8 Core, P440ar RAID Controller, 56GB of RAM and 600GB SAS 12Gbps HDs.
 What I have in mind with this server is to set up a few VMs:
 1 x SBS2011 (DC, Exchange, 32GB RAM), 1x W2012 Svr (as Terminal Server, 8GB RAM), another W2012 App Server (running Quickbooks, 8GB) for 12 users on the network.
 Having said that, do you think I would need 2nd CPU or it is an overkill?
 For the number of users and what they do, I think 1 CPU will work just fine.
 I am just considering it because we are in Virtual Server environment.
 I could also go with 1 CPU and add 2nd CPU later if/when necessary.
 
Thanks.

Thanks for your suggestions. It appears that 2nd CPU is overkill. I will go with single CPU with 8 core.

@robocat
when you said "more RAM instead", are you saying that I could use more RAM now with three VMs - SBS2011, W2012/Terminal Server and W2012/App Server and based OS (W2012 Hyper-V Server)?

@footech
I know SBS2011 is an old OS. But it comes with Exchange for free. Otherwise I would have preferred Small Business Essentials.

I am curious ... at what point/situation would you know that if 2nd CPU is warranted? Constant High CPU Utilization in Hyper-V?

I just discovered that I ordered 16GB module x qty. 6 . Since the server will come 8GB, I will have 104GB of RAM in total on this server.

"2nd CPU or more RAM, I would go for the RAM every time" ---> I will keep that in mind.
ok, 104GB RAM is a decent amount.
