Hi, new to this forum. I have a 2010 Mac Pro 8 core, 2.4ghz and I am thinking of upgrading to a 12 core. I note a few people have used the w3680 processors in the 2010 machine but only when it is single core to take it from a 4 to a 6 core. Can I use the w3680 processors as a pair? cheapest I am seeing these in the EU is around £175 a piece - does that sound about right? Am I also right is saying that for the 2010 Mac Pro you do NOT delid the processors but simply do a straight swap (after cleaning and new thermal paste etc)?
