I'll add my vote in for Asus. I recently purchased a G51J Asus laptop from NewEgg. Aside from the fact that NewEgg is phenomenal (I received my computer the day after I ordered it), it just great for Inventor and CAD in general. (games too, of course) I really wanted to have the 10 key numpad, because I use it all the time when CAD'ing. I did a ton of research, and went with this Asus because it really was the best "bang for my buck". Not to mention Asus has a great warranty on their products. The screen's huge, resolution's great, it's durable, and powerful. I love it.
