Few things to note about this laptop:
This computer doesn't have the greatest cooling system, but it's still effective. After 3 years of use, I idle around 62-69c in the Summer, and 56-60c Winter. The graphics card (Geforce GTX 260M) runs all of my games with decent framerates. (I hear that It can run BF3 well)
Battery life is under 3 hours.
If you would like to repaste the graphics card after a few years of use, you would need to disassemble the laptop.
Known problems:
Many people have reported screen issues. (For me, if the PC gets too hot, the screen shows green lines at a certain viewing angle.)
People have also had overheating issues with the G72. (If it starts crashing games after a year or two, you can fix the problem by cleaning out the fans.)
Advice: Make sure you..
Use the laptop on a flat surface, because the vents must stay clear to prevent high temps/overheating.
Do not press down on the side latches covering the USB ports. The one on my right side was pressed too hard, and broke off.
Download updates from Nvidia for performance boosts.
Repaste the CPU after 1-2 years to keep it cool.
