Rating: 5/5 This product is a fantastic upgrade October 4, 2015 The turnkey upgrade for 2009 MacPro models is the best upgrade I have ever had in my MAC family of products. The service and support was detailed and excellent. The product itself (replace processors and memory ) is like getting a brand new high end MacPro for less than the cost of the actual machine. The shipping, packaging and turnaround was simple and fast. Everything works perfectly and no additional user work is required. I highly recommend this product for power users that want to keep their older model Mac Pro- but recharge it with new processors and memory.

I would recommend this item to a friend!
