I already got mine.
Got 9141 on 3dmark05 running with all the crapware from dell, and without any driver update or tweak, that is running exactly as it came from dell. I just disable bluetooth and wireless.
The xps i had before with the 7900gtx, which I reurned due to bad screen and to get this one, gave me 8140 3Dmark05. That is an impressive 1000 increase.
The performance increase is also clearly noticeble on games as well. Oblivion is running faster and smoother, with everything maxed up. (Though riding the horse still lag a little bit, but much less than before)
FEAR extration point demo also ran like a charme. Fantastic when you use the new weapon and tear apart the whole office with that beast, no lag at all.
I got the LG screen, and I was surprised with that, because here in Canada, dell had been shipping the xps with the Samsung screen.
I was also surprised that the XPS is already coming with the new LED effects called XPS LightFX.
But one thing is gettting me: Seems that the 7950 GTX memory
is underclocked, according to specs given by nvidia which says that the 7950 GTX was supposed to come with 575 MHz core and 700 MHz RAM
Three of us who got the new 7950gtx is getting the same result, check here : http://www.notebookforums.com/post2470404.html
One more thing: on my Nvidia Display Control panel tab it shows that the graphics card processor is unknown. Go figure it<!-- / message --><!-- sig -->
