I run a 2012 MBP maxxed out and SSD, best machine ever had. Only got it as the 
2010 MBP ket rebooting with heavy editing use - graphics issue. The 2010 was 
handed down to my wife who obvs doesn't video edit or mash graphics - BUT as 
the years progressed, more and more websites require graphics intensive 
hardware as they get crazier with ads, video, you name it. So the 2010 started 
to fail again by just randomly shutting down.

Looked into replacing it, but the research threw up soem interesting stuff. It 
was originally thought that the 2nd graphics processing unit (GPU - MacBook 
Pros have 2 GPUs rather than a single in a MacBook) was failing by dry joints 
or what have you - and some reflowing repairs did solve some issues - but one 
guy chased the issue on the 2010 to a capacitor that regularly fails because it 
was *the wrong bit of hardware for the job*. Let that sink in for a moment. It 
was designed with an inherent flaw.

So, watched the video for the repair (see link below) and bought a couple of 
new caps (7 bucks the pair) and replaced one on the motherboard (a voltage 
controlling cap for the 2nd GPU) and hey presto - random shutdowns gone and 
machine in great health again.

Had to improve my soldering kit and technique but no biggy, and even with that 
the cost was a couple of dozen GBP and 3 hours of my time.

This guy is pretty interesting to listen to as well - he will readily slag off 
anything on the market due to poor design and workmanship - Apple especially! 
:-)

NB you might find links to the 2008 issue here as well.
