I have a 20" iMac G5 Rev A. I half brought it with my dad, but it recently moved into my dads office. Now I can hardly use it. So I am thinking of getting a new iMac I can't really afford the 20" Intel iMac so it would have to be the 17". My question is what performance boost will be like. I do use programs like InDesign CS2 and Illustrator CS2 - is this going to be a problem for rosetta? My specs: 1.8GHz G5 512 KB L2 Cache 600Mhz Bus Speed 2GB DDR SDRAM GeForce FX 5200 64MB 160 GB HDD Have they changed the screen at all from the Rev A's? Also I might want to hook up a 23" ACD later when/if i can afford one. How will the X1600 cope?
