Hi Sorry my English it's not too good, by I'll try to explain my problem . I've got a Macbook pro 17" with this generalized problem, distorted video and glitches. http://torley.com/macbook-pro-with-ati-radeon-x1600-distorted-video-glitches --> explanation Treated on this thread too --> http://discussions.info.apple.com/thread.jspa?threadID=1697470&tstart=0&messageID=12326867#12326867 I tried all that stuff, but no luck of resolving the problem at this moment. I thought i could try get a new logic board and ind the case get a higher one, but i don't know if will be possible swap the old one with a higher model. My actual model is this one. http://www.ifixit.com/MacBook-Parts/MacBook-Pro-17-Inch-Model-A1151-2-16-GHz-Logic-Board/IF187-003 And i would like to get one of those higher model's. http://www.ifixit.com/MacBook-Parts/MacBook-Pro-17-Inch-Model-A1229-2-4-GHz-Logic-Board/IF187-058 http://www.ifixit.com/MacBook-Parts/MacBook-Pro-17-Inch-Model-A1261-2-6-GHz-Logic-Board/IF187-088 it's possible to swap the older model that I've got the first one that has a core duo processor with the latest ones with a core 2 duo and faster processor ?¿ The chip-set looks pretty similar in shape and size. Thx in advance. P.D: I have to practice more my English. I'm from Spain by the way.
