Hey there Aiken, I'm new here and I have not yet decided if I want to buy this game but... I do own the same ASUS G73 as you!
You should really buy a AirCan and spray in the ventilation (to the right back) and this should be done every 6 months at least.
Why? Because dust can be caught in there (especially if you got cats, dogs with alot of furr) and this will bring your ASUS G73 temperature up and may result in bad performance.
I do have experience with Crysis 2, playing that on very high details and I don't have any real frame rate problem.
But yet again, I do have no experience with Brink but Crysis 2 is very graphical heavy game so if that game runs smooth I would guess Brink should too.
I don't have any better tip for you then to buy a AirCan and spray, make sure you read the informartion on the can before you spray!
[By the way, don't be so quick to jump the gun and blame the developers, many did the same with Crysis 2 but something simple as a AirCan solved my problem.]
Man, you really don't know anything about Brink. I run Crysis 2 fine with no problems, but Brink tricked us, the game is full of bugs and the one i have is Low fps due to the game not the PC.
And i have an AirCan and i use it one a week to clean my laptop with it.
