YES!
i got an alienware in august 2003, and people say they are overpriced, but IMO it has been worth every penny. yeah, you pay a little more, but everything i have tried to run (games/apps/etc.) has just run perfectly on it.
i just upgraded my alienware from 1 gig to 2 gigs of corsair XMS pc3200 400mhz ram, so i'm looking forward to even better performance out of it now.
i know someone is "giving" you thier alienware computer, but if anyone else is wondering, yes they are worth the money! and when it comes time for me to get another system, it WILL BE ANOTHER ALIENWARE!
