A laptop,
My Voodoo U709 is getting to show its age, and since HP bought Voodoo PC and has totally gutted them, to get the "true" upgrade, you have to either go to Alienware or Falcon NW.
I don't like the quality of the Alienware since Dell has taken over, as I find Dell has really watered down the quality, opting for very cheap parts, so I am leaning towards a Falcon NW "Fragbook DTR" which is the true upgrade to the Voodoo U709. It has an I7 Extreme processor and 3 hard drives. My Voodoo has an AMD 3800 and just 2 drives and 2 DVD Burners, but the biggest limitation is it only allows for 2 gig of DDR2 ram (and it only has a Nvidia 7950 GTX). I wanted to just get an Opteron 185 for it, but they still want about $350 on E-bay for that CPU.
