I am thinking that I need to ditch my G5 and get another Mac Pro. The G5 hasn't got enough grunt to do serious photoshop work let alone edit HD Video in FCP which is becoming, (rather annoyingly), a larger part of my business. My key Mac Pro is well upto the job at the moment (2x3.2 GHZ Quad Core Xeon with 32GB RAM) and I am thinking of getting something similar when the 2010 Gulftowns come out. At the moment my assistant and I can't really both work at full capacity because of the weakness of the G5. However I wonder whether I need to go back to the drawing board with how the machines will be networked and share files. At the moment I have a Weibetech eSata stack that houses 4 x 1.5 TB drives storing my digital picture archive. This is connected to the Mac Pro which in turn is connected to the G5 with an ethernet cable. Is there a better way of sharing these drives? Or of accessing files across machines? What benefits would a server provide? What about a raid card or fibre channel card? I really don't understand what benefits these could offer me. Any thoughts?
