The lights are on
Which is better Vigor or Alien Ware?
Its not so much a question of 'better'... a PC is a PC is a PC, no matter who tells you otherwise. an Asus P7 board is a P7 board whether its in an Alienware case or a Lian Li case... what makes one PC better than another is how recent the parts are and the configuration of those parts in context to one another. Also, the configuration in context to use.
My brother wants me to build him a firebreather... to play everquest I.... and chances are I could build him a PC with older parts and it would be 'just as good' because of the task.
lastly, and I really can't stress it enough - never buy the newest stuff because it's only newest for a month or so. Give parts a chance to be placed in all sort of PC configurations, read reviews on how they perform under various setups and then buy what you want.
But to answer the question - mainly you're buying a name. You more or less asked "what's better: CK or DKNY"

If I were you I would build my own for a fraction of the price. Check out the website How Stuff Works: How to build a computer for more information. If you build a custom machine your computer will be better than either of the computers you listed above and cheaper.
Well i prefer Alienware
Alienware is a great computer for gaming if you don't want to build one, but it is really expensive.
