I'd take Voodoo first, then Falcon. Simply because Voodoo has more models/options.
You may call it over priced, but I have never seen a disatified custormer from them. (Yes, they have unhappy customers like everyone else, they just take care of them better.) If you know nothing about computers, want something that looks awesome (<--understatment) and gives you the absolute best performance and customer service (oh yeah, and price is no object also...) then they're your reseller.
Alienware started the market argueably, but I have been less and less impressed with their products as time goes by.
It's bling-bling for geeks.
