So I have a 2006 Mac Pro, with the 2.66 Xeon and 12 gigs of ram +SSD drive. For every day tasks and web browsing, my 2.3 only feels a little bit slower than the Mac Pro. Safari tabs are a little slower, and windows pop up slightly slower, but I also do not have an SSD drive in the G5, only the Mac Pro. Obviously, if you start to tax the computer with heavier usage the Mac Pro is much faster. But it seems for web browsing, they aren't too far apart. Flash and video are the only issue, but it's not so bad. Any similar experiences? To clarify, my G5 is the dual core 2005 2.3, with 8 gigs of ram and a 7200rpm hard drive.
