Funny...with an SSD, new graphics card, and Lion I finally feel like my 2006 Mac Pro's processors are finally being used to their full potential.
People are so focused on the numbers they never noticed that these XEON chips often worked at half power because everything else couldn't keep up or take advantage of them.
The first-generation Mac Pro is going to be one of the longest-lasting machines I've ever owned. I'm 5 years in and I just now feel like it's working at its full potential. It'll be a few more years before I try and replace it.
Yeah I plan on keeping my '09 MP for years and just upgrading it. I'm going to replace my GT120 card with whatever comes out as a BTO option for the next MP, and add a SSD with Lion, sometime this year.
