I have experienced the common problem of Late 2011MBP graphics card "meltdown" and my 15" MBP has had all the crash problems that have been report on line by thousands of users. I am about to take it for repair. 2 questions: Can I ask to have a GeForce GTX 750MMac installed and Will it be garanteed to not have the same problems as the AMD Radeon HD 6750M which seemed to have failed from heat on the cold soldered elements. (in other words is the GeForce cold soldered? Thank you for your comments
