Asus G53SW Dota 2, still reliable?

[Amirteveh]

i have a g53sw running gtx 460m latest driver.
i play dota 2 on max graphic, it only gives me 15-25 fps.
Each time i want to play second game in dota 2, my laptop shuts down like i unplugged it during the loading screen to enter the 2nd ggame dota 2.
I need to restart my system everytime i finished first game in order to play more.
I disassembled my laptop, cleaned it, re applied thermal paste, bought vacuum cooler for the gpu fan and it seems no changes at all.
is this laptop already outdated? or only me having this issue?
SORRY FOR MY BAD ENGLISH. TQ !
gpu and cpu temp idle = 45C
gaming temp
gpu = 80C

80C isn't going to cause thermal shutdown or system instability. Your best best is to reload windows, reload the drivers and reload the game. Then you can test just the main components that use the game.

You should also test your ram and hdd to see if you have failing hardware. It might be a good idea to upgrade to an SSD at this time.
