Ok. Here is my situation. I have a mid 2010 15" MacBook Pro 2.4GHz i5 with the high-res antiglare display. For about a year the dGPU (Nvidia 330m) has been "glitching" under load. The display will blank or distort randomly. In the past few weeks I've been noticing it getting worse, like every time I try to scroll a website in Chrome it become illegible until I do something that makes the page redraw worse. Apple's repair program has long lapsed and I don't think it is worth the cost to have Apple do a depot repair or logic board replacement on it at this point. I've tried living on the integrated graphics only, but too many apps want the high performance card to perform on this model, and I regularly plugin to an external display at work. I'm thinking it is time to look to better options. I'm considering a few different options, some more practical than others. One less practical, but rather enticing is purchasing a used 2011 or 2012 Sandy/Ivy Bridge model with a busted or standard res display and swapping in out for the high-res display on my current machine especially since the antiglare option is a little more difficult to find used. I've done some searching and it looks like there has been some discussion along these lines related to 13" 2008/2009 models, but I haven't seen much related to 15" Unibodies. If anyone has any input I thank you in advance for sharing.
