Acer Aspire 5735 Motherboard Query

I asked a while ago about upgrading notebook's mobile graphic cards and was answered no.

Recently i had a idea, Hypatheticaly i could buy a new motherboard wiht a better built in graphics card installed. Is this possible with notebooks and if so how much aprox. and where/who to buy from.

 

Possible if you can find another Acer Aspire 57** series which comes with a better GPU, but the chances are pretty rare to find one. I'd look up ebay for either the motherboard itself or a notebook for parts. I'd say it's not worth the trouble. If you really want change, then you're better off selling your notebook for its market value and buying something that better suits your needs.

Edit: It seems the best graphics chip the AS5735 comes with is the Integrated Intel® Graphics Media Accelerator 4500M.

 

As Cheeseman already said, unless your laptop model is similar to the high-end Sager/Clevo models with upgradeable parts you will be wasting a lot of money for little to no return.
