Also, if you can find a computer with the ATI Xpress 200m integrated gfx, they're better than Intel's. (I'm pretty sure you have to get a turion to get the ATI, though)

they just came out with some new ones im not sure if they are big enough to fit a 17" laptop tho

off the top of my head i think a few acers are like that. the gateway nx850xl could also be an option, not sure if it has a 17" screen (wow i must really be losing it)
