Speed tests from <a href="http://www.MacTech.com/articles/MacTech/Vol.24/24.03/Office2008Benchmark/">MacTech</a> (like our forum name):<br><blockquote><font size=1>In reply to:</font><hr><p>For PowerPC Mac users, represented by our PowerBook G4 testing, on average:<br><br> * Word 2008 ran 35% slower than Word 2004<br> * Excel 2008 ran 65% slower than Excel 2004<br> * PowerPoint 2008 ran 9% slower than PowerPoint 2004<br> * Entourage 2008 ran 22% slower than Entourage 2004<br> * Graphics in Office 2008 ran 30% faster than Office 2004<p><hr></blockquote><p>i do most of my work on a G5 right now so my first priority is a new Mac Pro -- i just haven't had time to get the paperwork together to order it yet. doh.<br><br>but for Intel users, this is a good upgrade:<blockquote><font size=1>In reply to:</font><hr><p>For Intel Mac users, on average:<br><br> * Word 2008 ran 37% faster than Word 2004<br> * Excel 2008 ran 22% faster than Excel 2004<br> * PowerPoint 2008 ran 40% faster than PowerPoint 2004<br> * Entourage 2008 ran 28% faster than Entourage 2004<br> * Graphics (common to all the applications) in Office 2008 ran 60% faster than Office 2004<br><br>To make this even more clear, when something says "30"% faster," that means that if it took 10 seconds on 2004, it took 7 seconds on 2008. This tends to understate "faster" when compared to perception.<p><hr></blockquote><p>
