I am a long time Mac owner. I have a 2006 model 24" iMac 2.16Ghz Core 2 Duo, maxed out at 3GB of ram. The machine is tired, and needed replaced, so I decided that I could get more out of a Mac Pro than getting another iMac. So, I bought one yesterday on eBay. Specs: MA970LL/A Mac Pro 3,1 Processor: 2.8 Ghz Quad Core Xeon (1) Ram: 2GB Video: 2660 256MB I am fully aware that I can upgrade pretty much everything in here. Up to 32GB of ram, new video card, etc, etc. I was reading an older post on here regarding getting a new processor, but I have not found any concrete evidence as to what to use. I'll explain. The post I found had stated that the 2009 and up MP that were a quad core had one socket, while the older ones had two. Now, my machine is an early 2008, and I can only assume that I have one open processor socket, and could in fact buy another 2.8 W35xx processor and heat sink and I would then have an 8 core... Correct? Further to the point, I could theoretically get a pair of W3500 Series chips with a faster clock speed and really upgrade the machine. So if this is true, what are the acceptable limitations on processors I can use? As for the video card, I am reading all sorts of posts regarding the upgrade to better cards, but they require a flash to make them Mac compatible. To not have to go through that hassle, and still get a 1 GB Dual Link DVI capable card, what should I look for? Ram is pretty easy, and I understand the "matched pair" installation. I'll probably go through Crucial, unless there is something out there that is as good, but cheaper. Anyway, I plan on a quick 4GB ram kit and then reassess where I want to go, as I am working on buying a 30" Cinema Display to go with it. I have always wanted one, and now is the time. I'll be using the machine to do video production/editing and possibly multicam recording, as well as all the other functions you can do. I would really like to play Battlefield 3 on a windows partition, but it is not required. I can't wait for this thing to get here, but I am kinda glad it will take a few days. I need to clean out the iMac, as I have it sold and I want to have time to get the 30" display. I'll update as time goes on with what I find. The odd part about this, and it might be my ignorance, but every time I search the model number provided (MA970LL/A) I come up with an octo-core mac, not a quad. I just wonder if it was a misprint in the auction. I am not going to bank on an 8 core. I expect a 4 core to show up, but I want to be able to add the other 4 if possible, and upgrade the video card. What do you think? What should I do to make this a powerhouse, yet still be butter smooth and reliable?
