+12 core Build Centos/Vmware

[Tucan Sam]

So I am going for my VCAP-DCA 5 exam and need more resources, I am currently maxing out X6/32GB RAM/SSD
CPU- 16 core Interlagos [URL]http://www.newegg.com/Product/Product.aspx?Item=N82E16819113036[/URL]
mobo - Super Micro MBD [URL]http://www.newegg.com/Product/Product.aspx?Item=N82E16813182230[/URL]
32 more gigs or ram [URL]http://www.newegg.com/Product/Product.aspx?Item=N82E16820231486[/URL]
for 16core/64gb ram
~$1005
I am just not sure if the motherboard supports direct IOMMU I have SSD's and HDD's so I am fine there and a 6970 and spare 550ti(because ATI driver suck on nix)

I would prefer to avoid going dual socket if possible, this will be in my P182se and and kinda short on space as it is.

If intel has anything comparable for the price I am all ears I know, only thing I see is

I honestly would go with the SB-E and the dual socket board. You get more performance for your buck, and the SB-E chip has far better power management and a lower TDP.
