You can't go with dual i7 CPUs, for a dual processor system, you will have to go the AMD Opteron or Intel Xeon route for that. Go to newegg.com (link below) and look at server/workstation class mobos to see your choices. Good luck!
GOLGeek... thanks amigo... i will look at that list. Anything i should look at in particular? Anyway, u've pointed me to the the place where i can make some good decisions! thanks!
malmental... thanks 4 ur feedback... but like i mentioned, i'll be building out VMs so I can specify the number of CPUs to allocate to a VM or VM cluster... so wouldn't a dual cpu be useful in this case?
