make sure the disk is (or convert it to) thin provisioned.
sdelete -z in the guest then vmkfstools --punchzero from the esxcli.

can you run "cat /var/log/vmkernel.log | grep vector" from the cli on the host with the pass-thru video card? Post the results if there are any (do this after you reboot the VM)
if you set any type of cores per socket (less than 9 vCPU), you'll bypass the vNUMA scheduler and ESXi will stick the VM to a NUMA node

any more than 8 vCPU and vNUMA is automatically turned on

as far as cost, you can build a cheap server that will support 30+ virtual desktops for around $2500 - or use desktop components to go cheaper but you're still going to drop at least $800 on a...
you could try to stop the update service, rename/delete the datastore.edb file, remove the contents of the "download" folder, and restart the update service/reboot the server. That should wholly reload Windows update and force it to re-cache all the needed updates. I've had to do that a couple...
I just want to confirm your running some 180 databases from 7 VM with 1000+ users on 12 15k SAS spindles in a raid 10 that produces around 1400 IOPS (assuming 4k IO, 50% read, 50% write, and 10% cache hit) from the drives alone - not counting any caching from the SAN itself?
I'm going to go out...
CCA is not as comprehensive as the VCP. If you passed the VCP then studying for any of the CCA's should be a breeze. http://citrixxperience.com/ has some free study guides and some you can pay for. I used the site to help prepare for my CCAA.
