Best laptop , performance and durability (up to 3k$)

I'm checking out Killernotebooks, but was wondering in the main name brands, what would be best? Also I must add, I am in Canada (which makes me hesitate to order from KN)

basically good all around laptop, willing to dish out up to $3000.

15 or 17, smaller than 15 is way too small, and more than 17 starts to get kinda bulky

couple thoughts for you. Do you need vga or dvi connections for a "flame thrower"/ Projector? DVI-(A)nalog, (D)igital or (I)dual. Asus A8js was just released with Core2duo, and the Nvidia go 7700. Yes it's a 14", but it's quite powerful. As far as size go, that's the most powerful 14" you'll find, to my current knowledge. Asus A8js If you really hate being stuck on a 14 or 15.4 screen, spend a grand on a 23" display for your home/office.
15.4 lappy's seem visually to be a bit larger, and often range in resolution up to 1600/1200. The most powerful graphics i've seen is the 7600gt.. which is pretty darn good for most of today's games. Better than that for games gets you into the 17"+ arena. That will include more weight (about 1.5+ pounds or more), decreased battery life, Increased graphics potential (x1800/7900gs/7900gtx), increased screen resolution.
A 15.4"/15" can still be considered, semi-portable for business unless you're 5'2"/100 pounds. =P If you can spend up to 3k and WANT to spend that.. you could always get a MacbookPro fully maxed out, or a sony vaio.

Yes, excellent choices, especially since their configurable. Perhaps only one other I'd add is the Asus z92t. I think the msi looks better, but if you want Asus with AMD x2 and Nvidia..it's a good one. All of those choices would roughly be under 2k fully maxed out, depending on where you shop of course.
