So i should start by welcoming myself to Radeongate! Mac Book pro 15 late 2011 Absolute bonkers, what a fantastic machine to work with for 3 years and suddenly it goes blank! Its a real shame. No longer in warranty, i got the GPU replace from outside apple repair shop. It worked flawlessly for a month and the problems have appeared again. I have read and researched and it looks like this cannot be repaired. No sign of apple issuing a recall, what happened to Here's To the Crazy Ones. I am still trying to convince myself to buy a new macbook pro but the current options have somewhat left me confused.My late 2011 came with a discrete GPU and 500Gb HDD with core i7. I can no longer afford the new 15 retinas. So my main concern is how much would i be downgrading if i go for a 13 retina. -No dedicated GPU -A core i5 -A joke of a HDD space with 128GB SSD - High res screen (which may make downgrading from a 15 easier i hope) My main usage is photoshop and other image editing softwares. No gaming, just pure image editing. So i would just like to understand how much of a downgrade or a minor upgrade (with iris 5100) should i be expecting in terms of performance.
