Hi folks, I have an option on a 2011 MBP i7 15" with the AMD graphics chip (good deal with SSD and new battery). I've read online that there's been quite a few issues with the graphics chip failing on this model, so just wondering whether this would be a worthy purchase in 2018 - I'd be interested to hear if anyone has any insight on what the likelihood would be of running into graphics-related issues with this. I'm looking for a 15" MBP and this deal is pretty good money-wise so just wondering whether it's worth the risk, or if I'd be best steering clear of this particular model. Any feedback is welcome. Thanks!
