I have an Intel MacPro about 17 months old. Processor: 3 GHz, memory: 13 GB, hard drives: striped RAID 2 WD Raptor 150 GB drives, 2 Seagate 750 GB drives for data storage, backup & alternative systems (like 10.5.1), OS 10.4.11 on the above mentioned hard drive or OS 10.5.1 for testing & watching video artifact lines, Video cards: ATI1600 running the Apple 23" (1920X1200) & 30" (2560X1600) displays, Nvidia 7300 GT running a 28" ViewSonic (1920X1200) & Westinghouse 47" (1920X1080) displays.
Excel scrolls at a normal speed, sometimes faster than you want. Excel 12 is even slower now than when I made my original post. Most like 5 seconds for a fast scroll or page up or page down.
Everything runs very fast other than scrolling on a like sized Numbers spreadsheet. So who copied who on this point? That leaves all of the many programs that run in the background or foreground. Also I have both version of Excel on my system (11 & 12). With other versions this has not made any difference.
