So I got and setup my new Mac Pro two days ago with the following specs: • Processor: One 3.20GHz Quad-Core Intel Xe • Memory: 3GB (3x1GB) • Graphics Card: ATI Radeon HD 5870 1GB • Hard Drive Bay1: 1TB 7200-rpm Serial ATA 3Gb/s I mainly do photography, web design, graphic design, videography, some gaming on Steam. My last "workstation" was a 2009 Unibody MBP 15" so this is considered a huge upgrade. Running the programs I need for my work at the same time I will get the beach ball such as importing clips to FCP while working on PS C5 and importing my 35GB of mp3s back to itunes. While gaming DOD Source is as smooth as a baby's bottom running the recommended settings at 1080p res. TF2 I haven't had the chance to try yet. Everything runs smooth, but would be even better with more ram and SSD HD boot drive. I have already bought 24GB of ram and will be installing that soon. As for an SSD I will be getting the 120GB OCW SSD to boot from. The stock 1tb is enough for me right now as I store most of my files externally other than the most recent files which I store on the Mac Pro and back up on another external. Missing esata kinda sucks but I bought one to remedy that. Hope this helps those who are considering this machine.
