What will I be charged to fix this

my Apple 17" laptop has this not as bad as that though but I guess it'll eventually get like this.

What do you think are the estimated repair costs? Annoying coz the laptop is a bit slow for the kind of stuff I do but its a gorgeous laptop.

It was the radeon 9700 mobility I think.
It was the 1.67Ghz revision.
