Hi guys, My name is Daniel, and im new to this awesome forum. Im seriously thinking of buying a Mac Pro Quad Xeon (1.1, 2006 model) that I saw in another forum for only 800, so here is my first question: If I buy it, I'll make some upgrades: 1- Replace the 250GB HDD with my 120GB SSD 2- Replace the ATi Radeon X1900XT with a Radeon 6870 (probably: http://es.msi.com/index.php?func=proddesc&maincat_no=130&cat2_no=137&prod_no=2144 or http://es.msi.com/index.php?func=proddesc&maincat_no=130&cat2_no=137&prod_no=2106) 3- Replace the 2 CPU's with 2 Quad Xeon L5420 (in the same forum I saw one for 50, so I'll have to buy another one from eBay), making 8 core in total. The question is if that Quad Xeons will work well, because the upgraded 1.1 Mac Pros that I saw on many forums have been replaced only with X5355 models (http://ark.intel.com/Product.aspx?id=28035), not the L5420 (http://ark.intel.com/Product.aspx?id=33929), and they use the SAME socket (LGA771)... So well, what do u think, will they work or not?, as the Intel page says, the X5355 has "65nm litography", but the L5420 has 45nm... I don't know if that makes sense, but well... if they are the same socket what's the problem? Thanks in advance, Daniel.
