Hopefully they can get the cooling right in such a thin case. I had a Sager 8760 with the ATI HD 5870 for about a week before returning it and they were able to pull it off, but the form factor wasn't nearly as nice.
I really dig the built-in Eyefinity support, E-Sata and USB 3.0 on the HP. Will have to wait until the 19th to see what kind of configuration options and prices will be though.
Its a great notebook,but your sager has better specs + better cooling,so IMO keep it,unless you care much about the looks and need USB 3.0
Is HP just buying the old VoodooPC Envy which was, at least in past years, a Clevo build ?
