CPU/GPU combo is the way to tell you what most gaming significant pieces of hw i have on this box, everyone knows what I am talking about, since you don't, I have to be a bit descriptive, CTD 6320/GA 865P DS3/8M DDR2 800/GF 8800. BTW, its CPU/MB/RAM/Video card combo.
Xeons? Don't make me puke, I donated my last Xeon box a few years ago.
