Chosen Solution
Hypothetically, Assumed my iMac’s GPU burned, and I need to replace it. What GPU would you choose, and why? I mean there are lot of stories that I can put better GPU and enjoy the games and so on, but what about Power Supply, will it be enough watts to feed stronger GPU? And do I need run my fans faster to keep it from burn? And opposite side, if I just need to got cheapest GPU which will allow me to work on this machine (no games), what will be the best choice? Thanks in advance!
I had this same machine in today with a bad GPU. Pulled the logic board and used a hot air rework gun on it for about seven minutes (did it slowly) to reflow the solder. Works great now. Just something to consider. The machine runs about $60 on eBay ( you can then resell the machine). UPDATE https://www.youtube.com/watch?v=hoxR_TVE…
While some people have managed to frankenstein their systems with odd MXM II boards I strongly recommend you stick with the correct parts this system was designed to support. To that end here goes: 661-5944, AMD Radeon HD 6750M, 512MB 661-5945, AMD Radeon HD 6770M, 512MB These are what your system could be ordered with.
