Quit makeup the bullshiting thing. Photoshop, Video edit, and dvd movie.
In fact,
Photoshop- HIGH RAM and CPU (high FSB)
Video edit- high speed hard drive or RAID 0 (high caches and data transfer rates)
DVD movie- CPU
graphic engineer- If Autocad then nivida Quadro is best one and it cost over $1k and it is not for gamer.
I stay avoid from gamers laptop due overheat, very limits to upgrade, and drain the battery so quick, slower than most desktop. I like to built the desktop for gamers over laptop. So I use my laptop for travel a lot and battery life is around 8-hours. I am very happy with that. It use Intel GMA and run smooth on photoshop, edit video, and dvd movie but it won't support blu-ray so dont really care about that. I know someone who own old laptop is 9 years old (no upgrade hardware/OS and no re-install OS) and it run smooth on dvd movie.
Upgrade desktop way cheaper than laptop. That's all I spend $300-$400 (cpu,ram, and gpu) each 2-3 years for newer gamers vs spend over $1k laptop gamers with limits upgrade, hardly to replace GPU and CPU.
