    eerrhh... no one have this kind of problem too?

    anyways, the performance is pretty good, i can pay games such as DMC4, sims3, and the last remnants without any trouble. it does get hot, but i think it is still on a normal temperature for a laptop when used for such task. my sony vaio laptop is even much more hotter when i use it for regular task such as browsing and typing documents.

    well, the screen brightness is the only problem i've had so far....
    any reason why your friend said so? AMD is one of the best processor manufacturer in the industry, i wouldn't doubt its quality...

    my friends say that amd processors are prone to overheating and they work properly for 1-1.5 yrs n then start giving trouble...thats why i'm a bit scared of buying it,but i like it ..

    Um.

    Im not sure if i have the same problem as you but,

    Sometimes after I put my computer to hibernate and then turn it back on, the Fn brightness hotkeys don't work.
    Anyone else getting this?

    @hitme666, i think it will be fine as long as u dont overclock it.

    @accuracy, im not sure, but in my case, the fn+f5/f6 gotkey does display the brightness meter change, but the acual lcd brightness doesn't change until i restart my computer, and this happen all the time,
