So I have maxed out the ol' iMac with all the tricks you can teach a pony. In other words, it's too slow now with HD footage and esp. since i have taken the jump into COLOR and will be with SHAKE and AE. I am a one man user of the whole suite and would like some advice from someone in the same boat. I will be buying a macpro this summer and am trying to decide if the $2600 upgrade to the 2.9ghz cpu's will be cost effective for me. It seems as though I waste the most time rendering (COLOR and FCP but no clue in shake). PLus it seems with the HD footage I am eating a ridiculous amount of hard drive space with the apple intermediate codec, does this mean that I have to load up on 4 x terrabyte drives?
