I'm putting together a dual core AMD system (4200+) for that price... much beefier. I don't know why you'd want to spend almost $1500 on a new rig and not dual core it.
War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature, and has no chance of being free unless made or kept so by the exertions of better men than himself.
-- John Stuart Mill
