I would like to know if the above processor is compatible with the Mac Pro mid 2010 model since i think that the westmere 3.33 model is too expensive, i was after another cost-benefit solution that would still get me a six core processor boost.
Xeon Six Core E5649
Ant suggestions and comments, please feel free.. im new to the mac hardware world, but have great knowledge on PC hardware assembly.
If you're looking for the jump in performance I do believe you can upgrade to any chip that's listed as optional on the Mac Pro specs. You'll want the 2x6 core chips for the 1333Mhz speed bump in Ram, which are the W3680, the X5650, the X5670 and the X5675. All of which should work with your '2010' Mac Pro as all of the Mac Pros 2009-2012 share the Intel X58 chipset/mainboard.
Again, don't follow my words like scripture, there could be some inherant compatibility with certain chips. I'm in the same boat as you with a 2010 Pro and will probably be doing something similar later this year.
