Old G74sx with dying Nvidia Geforce GTX card- is this replaceable ?

[covergirL]

Have an older G74SX with a dying Nvidia Geforce GTX 560M. Love this laptop and it can still play Steam...
Is this graphics replaceable and whats the fastest card i can replace it with?
I am moderately tech repair savvy (replaced laptop screens, iphone screens and batteries etc) so if it is possible, if anyone could get me detailed directions.
thank you.

You should Google the subject (there were several graphic cards made to adapt to work in that old laptop).

Honestly, it's not worth it.
