Can't make my mind up between having:

Dual Xeon's at 1.8GHz (Nehelem architecture, no Hyperthreading), so 8 real cores total.

Or just a single i7 950 at 3.06GHz, so 4 real cores and 4 virtual cores.

What do you guys think?

Our CPU loading isn't expected to be that high but it will probably end up running about 10 or 12 VM's eventually. It will have 24GB memory.
 
Xeons', assuming they will be running on a 771 esque motherboard running VT and FB-DIMM etc.
 
Are you building your own machine for this?

I would strongly advise buying a server from HP/IBM/Dell etc for this purpose.
Since you are running a lot of machines you really want dual PSU, NIC and all the other fault tolerant stuff servers can provide, and the safety net of support from the manufacturer.

This in a roundabout way answers your question as you could only get Xeon processors (or the AMD equivalent) in a server from a reputable manufacturer.

You will almost always tend to find that you're going to run out of memory before your CPU becomes the bottleneck, so I would worry less about the number of processors and more about the maximum memory capacity of the machine.

(These are generalisations, it really depends on your usage)
 
Budget is the issue. A HP/Dell server of this spec would cost several grand.

Whereas the few I've spec'd up are coming in around £1200-1300. This is with Supermicro/Tyan motherboards.
