Ok, well I dont know where else to ask this question..
I want to run 4 VM's but i am not sure which VMWare to use.. so many different types you can download ..like Vsphere? the VM's will be cisco, like call manager for example.
Additonally, if anyone has some input on the hardware specs i need to build a server, it would be appreciated. AMD Opteron 6128 Magny-Cours looks nice 

 but if someone has some personal experience, that would be great... edit.. just read thats it difficult to get cisco vmware to work with AMD proc.. do'h~!
budget., 1500.
use : LAB- 4 vm's and when im not using it for the lab.. file storage, ripping/encoding iso's/movies/game backups/etc.
Thank you!
