Taking a quick look at the Boxx Technologies website it appears those are the same rebadged ODM laptops as most others have.
Here is the thing, especiually for audio, and still is true for video for different reasons...
Buying the most powerful laptop out there probably isnt the best idea. If you plan on doing any recording on it, I hope you dont mind the sound of a jet turbine in your recording as most of their cooling systems sound like one. I used to think that it was better to do this, but now I really dont. I think it is much better to get a stable and quiet system than it is to go with high powered. The reason is, typically for the difference in price, especially with PC notebooks, you can buy yourself a much more powerful desktop to do some more serious work on as well as the laptop to use while travelling around.
Most of the really high power notebooks at the moment all are tethered to the outlet anyways otherwise their performance suffers as well. Their cooling systems are obnoxiously loud, and IMO as a result of running so hot they arent quite as stable. I have gone through to many laptops already that overheated on me when in heavy use.
The reason this still holds true for video IMO, is because for video you wont get a truly good video rendering station on a laptop like you can on a desktop, video is much more resource intensive. Or if you do, you will be spending enough to buy two or three desktops to do the work, and the desktops could probably do a better job at the moment.
Pentium M chips have been used a LOT in mobile recording, and are typically more prefered than the desktop chips because in actuality the difference in power is pretty small, and they are much lower power meaning less need for cooling. Video Cards, especially PCI-E, can be the bane of your existance with low latency audio recordings depending on the chipset used, nForce4 is a well known problem in audio, with a few exceptions, unfortunatly I doubt you will find those exceptions on a laptop if it has that chipset for whatever reason(Honestly I dont know if a laptop that uses AMD and PCI-E would use the same chipset as the desktop or not) They also arent as important in video, some 3D effect generating applications can use them, but for straight editing/transitions/ and the like they really arent that useful, yet most super high end laptops are actually designed for gaming so they come with the latest greatest that has to be cooled.
Anyways I would bet you get the gist of my post by now
