We have three Early 2008 Macpro's 2.8Ghz macs with 14 Gb of RAM installed and when moving images around within documents they are so slow, in fact to the point of being unusable. Also they are quite hesitent when resizing windows. The Macs themselves are running 10.8.4 and CS is also fully updated. The Macs only have the standard Graphics card in them the ATI 256Mb card i had considered upgrading this but, i didn't think Indesign was that GPU hungary.
Any ideas to help speed things up much appreciated.
