I’ve got a mid 2015 15-inch MBP that had the GPU go bad earlier this year. Lately I’ve been using it docked to an EGPU which seems to resolve the issue (by bypassing the internal GPU I assume), however, now I’ve essentially got a desktop and I miss being able to take my laptop with me. A replacement logic board is about $400 on eBay (with guarantee and return policy) and I’m fairly good with electronics (I could even upgrade to the 2.8ghz cpu over my current 2.5) and I’m sure I could do the repair myself. My question is if it’s worth it? I’ve never had any speed issues or desire to upgrade, but investing in old hardware with used parts does have a risk. As far as just replacing it, I don’t want a butterfly keyboard, and I can’t afford the 16-inch model, plus considering that Apple is switching away from Intel I feel less confident investing in that architecture considering how long I’d want to keep the new machine.

Thoughts, opinions?

Thanks.
 
I have a mid 2015 - love it - you can get a used one for around $700 - $900 - Am assuming the new board would be with 16g mem and i7 processor? also you might want to factor in a new battery? SSD upgrade?

Yeah I really like mine too. The new board is 2.8ghz i7 and 16GB ram. I actually just had the battery replaced by Apple a few months ago with the recall program. I was considering an ssd upgrade, I’ve got 500GB now and I’m pretty happy, but a 1TB Samsung Evo 970 and adapter can be had for under $200 - which is tempting...

i got the same macbook, i really love it and thinking this is the best macbook that apple launched in 10 years at least.
i think you can find second hand used ones for 800$ its worth more than just replace the logic board.
get a new one and find a logic board on to go sometime.
i have a problem with mine too, im looking for replacement screen for my macbook pro 15" mid 2015.

The 2014 and 2015 MacBook Pro models were the pinnacle of their respective generation that eliminated the flaws of the 2012 and 2013, arguably better in some ways than the 15-inch that followed, and have proven themselves to be very reliable systems. The biggest issue I would have with a used board would be if a seller was offering it because the dGPU was showing signs that it was beginning to fail but not quite at the point of all-out failure. If you have a solid warranty on the board and are okay investing the time, I would buy it, install it, and stress test it to ensure its integrity, and then enjoy a computer that will probably remain relevant for another half decade. Further, a good condition 15-15-inch dGPU model is easily a $1,000 computer, so it's not like you are going to find one on the used market for less than the price of a logic board.
