How can I tell if a replacement logic board I want to purchase online is the new updated and revised board?
What’s the part number of the board you want? Please give us a link nowhere you heard about this board? Why do you want this board? There are both i series boards and Core 2 Duo boards and at least two each of those. Please be much more specific about what you want, what CPU and what you have now. Your question is just to vague to answer as is.
Apple do not make revised logic boards, they simply replace a board with a replacement of the same model. For example, with the 2011 Macbook Pro 15 GPU issues, they were replacing bad boards with the same boards, which have the possibility of failing again. You need to find a board with the logic board number 820-2850 if you want to replace this. If by any chance, your Macbook was crashing and showing kernel panics, you (or someone else) needs to replace C9560 on the logic board which will resolve your issue. This commonly fails, causing issues with the GPU, since it stabilises the voltage line for this.
