I love mine , i got it a week ago and saved 300 bucks through my company discount. I got 80gig , 1gig of ram, 1.86mhz , true life, and got a ditty free and free shipping. Total came out to 850 with tax.
But i love it and im glad i got the XPS. As far as games I only use my computer of World of Warcraft and belive me it runs excellent on it and i have most of the settings on high... Im sure that other games would not run as good but i have the xbox 360 for that
