That looks very similar to the 7500 I just bought from Alienware. Bottom line I had the thing for about 6 days total and had to ask for a refund. Be it the beta video drivers for the 8800 video card or just plain Vista, it blue screened on my constantly. I spent the first 3 days trying to fix it myself, the next 2 days doing everything every tech they had suggested til they asked me to send it back. Sent it back, got it back again in about 2 weeks, not the same problems, but just as many different ones. I just wanted to play World of Warcraft and Dawn of War on it and I never got to do that for more than 21 minutes before crashing. Not willing to dump another 70 hours troubleshooting it again I told them to take it back as they had assured me it would be fixed when I got it back and it wasn't.
I was, and am, very upset. I'm out the shipping both ways, I'm out 15% of the cost to "restocking fees", and I'm back with my old computer. Which is a 6 year old Alienware that I have never had any problems with it's just it's 6 years old and I want more fire power.
I wish you much better luck with yours than I had.
