Asus G75VX

There are several different models, I've got a G75VX-T4014H (i7-3630QM, 8GB, 256GB SSD+1000GB HDD, GTX670MX, LAN+WLAN Atheros).
I've installed Ubuntu 12.10 64bit in UEFI mode without problems after playing a bit with the BIOS settings (CD Boot was off) and removing all partitions except recovery and Win8 primary, dual boot via Grub2 is fine.
Using proprietary nvidia-experimental-310, no problems so far.
Weakest part spec-wise is the WLAN/Bluetooth chip Atheros AR9485 (bgn 1×1, 150MBit only) but Linux support is fine out of the box - I suppose the Broadcom chip in the other models is 802.11ac without Linux support.
I would have expected a 3×3 450Mbit model on a laptop of this class instead. Additionally swapping it will not be easy and probably void the warranty.
I also tried a Netgear A6200 USB adapter but no driver as well.
This is really a nice machine, very quiet for a gaming laptop.
2 HDD and 2 RAM slots are easily accessible after taking of the back cover and for 8GB models like mine the installed 2x4GB are under the keyboard so RAM extension shouldn't be a problem provided the sticks are compatible to the installed ones.

This is was designed to be a windows 8 gaming box, and it says “Republic of Gamers” all over it. I got it for the i7 processor(s) and the nvidia video to do video processing. So far (2 weeks) it does that very well with kdenlive on Ubuntu Studio 12.10 with just the stock 8Gb of ram. On the Windows 8 side it's still under-powered (ram) for Lightworks pro. I got it anticipating the upcoming Lightworks for Linux release.

This is still a very new laptop as of this writing and has some of the glitches on Linux that entails. If you aren't familiar with installing Linux on unsupported hardware, you might want to avoid this laptop for a year or so. I've installed Ubuntu 12.10 and had the following issues:

• Dual boot issues: WARNING - This is a UEFI system! Read about Linux issues with UEFI before doing this. I installed Ubuntu 12.10 ok but was left in an unbootable state (wouldn't boot into grub2). I was able to use the Linux-secure-remix (64bit) boot rescue CD/DVD to get it booting. It now boots Windows 8 and Ubuntu 12.10. It shows both bios and UEFI options, some of which won't work depending on the bios settings. http://sourceforge.net/p/linux-secure/wiki/Home/ Go to the “Files” and make sure you get the 64 bit iso. The 32 bit iso will refuse to work on a UEFI system.
• NVidia driver - Needed to install nvidia-compat package to get this proprietary driver. It works OK without it, but why pay extra for this laptop if you're not using the GPU ? Note that the nvidia-compat package is not the latest Nvidia driver, which may explain the chrome lockups mentioned below.
• Wireless - The Broadcom 43b1 (rev3) - This does not currently work with Linux drivers. I had to use ndiswrapper to load the windows XP bcmwl5 driver, which I got from the asus site: http://www.asus.com/Networking/PCEAC66/#support_Download_17
• I've experienced occasional X lockups when trying to view videos in Chromium-browser. This can be dealt with by ssh-ing into the system and killing all the chromium-browser processes. This will hopefully be solved eventually with newer nvidia drivers.
• Battery: This is a Lithium Ion battery. This means that the charging circuit must shut down charging when full or risk overheating, fire and numerous bad things. If you leave it plugged in when turned off, it can get stuck not charging. This can be a problem in either Windows or Linux, and require shutting down and re-seating the battery. Not an OS related problem.
• Battery: given the small size of the battery and the severe horsepower this laptop packs, the battery life is rather short, about 3 hours if you're lucky and don't push it.
