>The issue is POWER. To a point. Adequate rather than optimal in my case... 'Am hoping that going from: a 800 MHz G4, 133MHz bus, ATI Mob Radeon 7500 with 32MB vRAM, 1 GB RAM to: a 2GHz G5, 667MHz bus, ATI Radeon 9600 with 128MB DDR SDRAM; 2 GB RAM [with a 1680 x 1050 screen thrown in (iMac)] will be an adequate power boost to keep FCP performing reasonably for about $2k . To go with a (fabulous) dual 2.3 plus a 20" screen plus 2GB RAM is about $3.3k So, unless there's a killer caveat (?), the iMac (with hack) looks like good value.
