look at HP's laptops.. i just bought a fully loaded entertainment level laptop from them, it has two 7200rpm hard drives, 17 inch screen, plays HD stuff, has the HDMI port, blue ray, etc. i've been playing games on it and the graphics are pretty darn good. I've logged plenty of hours on both HP's and Dell laptops, but i've found a happy spot with my HP laptop :-)
HP's extreme multimedia laptops have some unneeded stuff like the screen tilts at angles and stuff like that, soo don't forget to check out the 'entertainment' level laptops.
