I really need advice: This will not be my first upgrade, I've replaced my optical drive with a hard drive and my hard drive with a hybrid drive. I've maxed out my ram, but I'm not satisfied with the performance. I am not upgrading because it would require me to lose my 1.75 Gb of storage. I currently have a 13" 2.66 Ghz Intel Core 2 Duo mid-2010 Macbook Pro. I want to replace that logic board with either a 2.3 Ghz Intel Core i5 or a 2.7 Intel Core i7 Sandy Bridge pulled from a 13" early-2011 macbook pro. There may be a few other parts that don't match quite up between those years (EX:iSight camera, bluetooth,airport card).Can anyone tell me specifically what I will need to buy and replace in addition to the logic board for this particular upgrade? Also, are these two models alike enough for this to actually work? (Please only address these two questions. My mind is made, the cost of the logic board is not important. There is a similar thread, but it is a different year and size).
