Pretty much agreed on that. You need lots of RAM to do VMs well though. I've got 18GB, and I can run vms pretty much to my heart's content. Would hate to try to do that on a 2GB box.
RAM is cheap though. I recomment 8GB minimum if you're planning on stressing your computer. One of these days, I still plan on maxing my box out at 24GB. Even with 18GB, I've managed to max my box out a couple of times. (Pegged all 8 cores, and all 18GB GB of ram doing some statistical analysis of some rather large data sets.)
You’ve reminded me of the little ‘power plant’ at work that I built. hehe
An ESX Cluster with 396gb of RAM and 24 Xeon Processors. Was able to shrink a good part of our data center down into a couple of cabinets. (one for the cluster and the other for the EMC SAN)
It’s fun when they actually let you spend real money once every decade or so....
