GPU Panics - not solved by logic board replacement

I have a Mid-2012 rMBP. The first logic board had sudden GPU panics and crashes until the board eventually stopped powering on. Since it stopped powering on, Apple refused to replace it.

At great personal expense I have imported two different logic boards to Canada and performed the replacement. The exact same crashes persist.

So I am starting to think that this may be not a Logic board issue - and I am looking for help tracking down the problem.

Thank you.

You're at the point where it may no longer be worth the effort in spending more money in an attempt to fix it...

Check the MagSafe board
That's a fantastic idea. It stands to reason that a failed magsafe board could mean the GPU is not getting enough juice, (this might also be a cause of the check battery indicator I am getting on my 500 cycle battery). Time to watch a teardown.
