Replace nvidia GPU on Penryn MBP ?

I still have a 2008 Penryn MBP that most likely fell victim to the batch of faulty GPUs. Unfortunately the MBP was a few months out of the 3 year apple care period when it started showing graphical artefacts and the random freezing, so I set it aside. At some point I realized that apple extended the replacement policy for these issues - unfortunately, again only just a few months after that program had stopped.

As I would hate throwing away a good piece of engineering and a (presumably) otherwise fine computer (battery needs replacement as well ofc.), what are the odds of fixing the GPU?

I have read about people baking their books to the effect of rebonding brittle solder joints. In many cases to no or only temporary success. So that is not something I would pursue.

Then, there are online services offering repairs (in Germany) that have received less than stellar reviews (people not getting their stuff back, getting it back without problem resolution, fighting over money ...)

Does anyone know of a solid option on getting this brick repaired? Preferably in Europe/Germany?

If it is not possible to repait it, what are the chances of salvaging components? I really do not want to turn this thing into material waste, even if the cost effective solution would be to dump it and get a replacement.

Thanks.

that may prove to be difficult. ebay is apparently full of penryns with defective gpu/logic boards

well ... they sell for about $200 - but I'm not trying to salvage money from this MBP. At that price, it makes financially more sense to keep the brick and leave it sitting on the shelf as a solid reminder for whenever the iWant syndrom sets in.

Guess I'll try my luck with the apple store and see if they can make a sensible offer for the repair.
