Autocad 2006 on a laptop?

Friend wants to buy a laptop. He's in college and learning CAD. He uses AutoCad 2006 and is new to the software and the realm of laptops as well. He's asking me what laptop to buy. I've suggested something with a large LCD, good processor and lots of ram.

 

Anyone know how well AutoCad runs on a Dell laptop? I have the XPS m140 myself and I know the integrated graphics are pretty horrid for anything graphically challenging.

 

Should he be concerned about haivng dedicated video memory?

 

thanks in advance for the replies...

 

unless they are just plain cocky ;)
