Since gaming is THE GOAL, then you would look for a ultra high end video card such as part number A0347986 RADEON 9800 PRO 256MB AGP in some Dell XPS Laptop.
That should do it.
I am looking for a gaming notebook, but don't know what to choose from. What are some of the best gaming notebooks available and what specs would i be looking for in one? Size, weight, or battery life isn't really a factor for me since I will be using it as a desktop replacement.
