Hi, at the moment I have a late 2007 mac pro: - 8 x 3 Ghz - 10 GB 667 Mhz Ram - Ati Radeon 1900 XT 512 MB I bought it only because I got it for a very, very good price one year ago. I only paid 1700 Euros for it. But I thinkt that I don't REALLY need such a monster machine. If I didn't get this offer I think I would have bought the 4 core only machine from Apple. I use it mostly for photography (Lightroom and Photoshop) and also some video stuff with Final Cut Pro. What bothers me with this machine is that it sucks so much power. The 3 Ghz CPU was the fastest and most expensive BTO option you could get for the late 2007 model. The graphics card also sucks alot power and is VERY loud. So right now I think about replacing it with the new 2009 2,26 GHZ 4-Core Model with 8 GB of RAM and investing some money on buying two Velociraptors in RAID0 as System/Apps drive because what I experienced with my current Mac Pro and Lightroom is, that the speed of a standard harddisk is the bottleneck. Also the 2009 model sucks less than half of the power and is alot quiter. My current Mac Pro is like a radiator in my small room. With the graphics card it sucks constantly about 400W. My question is how does the new 2009 4-Core Mac Pro compare to my old 2007? What do you think?
