AMD Radeon HD 6770M on iMac can be replaced by AMD radeon 6970
I am having problems with my GPU, I do not want to buy a new iMac if can be fixed and even better upgraded. I know I can try to find the same, except GPU, but I want to know if I can get more than 512MB on video, making opening my iMac worth it? BTW, mine is iMac 2.7ghz 27 inches with 512 video card.
Thank you again, I do not know if I could attach the image well, I try answering but I do not know where it goes, so I edit my question adding this image and looks fin on my computer.
That time that screen was like in the picture, the computer after few seconds reboot and start again. the next time was black screen and I have to shut down by pressing the start button for few seconds.
I am pretty sure I am able to turn on my computer again but i want to keep it alive until i found the proper solution or replacement.
Looks like I will need to get the tools to open my iMac and learn how to do it, anyway is not working, so is a good excuse to try to fix it. Its a shame because the screen is really good, those 27 inches are great for my eyes and for editing.
I know is an old computer and until last year I was very happy with it. so I hope you can see the photo and might be give you a clue what can I do.
Thank you so much.
