Actually, I have a two questions. So, I'll start with the quick and easy one. I just got this 2009 Mac Pro and have already flashed it to 5,1. So, hurray for the easy part. Now, without doing anything else can I buy 1333 memory and install it right now with the original 2.66 quad still inside. Or do I need to change the CPU to either a w3680 or w3690 first before the 1333 memory is usable. Second, is this the same as a "w3690" that I can use in my computer? If it is, I was considering buying this system, hacking it apart and selling the pieces to more or less recoup some of the cost. The average w3690 goes for around $300 and the average w3680 goes for $230. I know everyone says it's only a 5% difference but I figure, why not get the best one now if it's not that much more just so I don't have to sit and think. Wonder if this would encode video faster if.... http://www.ebay.com/itm/Dell-Precis...1095030556?pt=Desktop_PCs&hash=item5412f0e71c Thanks everyone, I need to get this computer up to snuff soon. I had a Maxed out 2006 Mac Pro that would more or less run circles around this one in every area. So, hopefully after a few updates I won't be thinking that anymore. And lastly, just for kicks. I am thinking of going 2x8 on the memory. I'm not sure if I'll need more than 16 gigs in the near future, but I can always add another 16. Is this right or should I just say F it, throw it on another credit card and get 1x16 with the knowledge that I can also add from there. Not cost effective. So, scratch that, I'll go with the 2x8 as I'm fairly certain anything else just sits.
