Brad While first gen. G5 are great but still a bit costly. And the Mirror Door G4 is simply loud (if you don't get a fan upgrade with your purchase)... I would look for a max out Quicksilver (2002) with a dual 1 GB processor and 1.5 GB of memory. That what I did and it fill my needs for now and runs my small rep firm as well. And yes, I using OS X 10.5.2 (Leopard) Mine cost me $260.00 and and shortly there after I sold my QS 733 MH for $200.00... for a difference of $60.00. via ebay. Granted I was lucky but one should be able to close on a QS (2002) for under $450 easily. By the way be sure to get a QS 2002... because the QS 2002 do not have a limit on the size of hard drives attached and had a faster processor chip and in general a better unit to work with and easier to upgrade and build-out. I've max out everything I can on this model, include a 750GB second hard drive with firewire as a backup device. Bottom line - the QS 2002 has a good cost value and still handles Leopard! Good luck and good hunting! Rich aka therepguy Houston //////////////////////////////////. On Jan 31, 2008, at 3:54 PM, Brad Russell wrote: "Still a little confused. When you say "specifically, when I scroll from message to message in my inbox is when it is less responsive" you don't mean actually switching from message to message but simply scrolling in the message window? I don't know why that would be any different than scrolling within a particular email itself." Sorry I'm not being clear. Simply scrolling in the inbox window is sluggish. But scrolling in the reading pane is fine. Also, Thanks for everyone's advice! I think I'm convinced not to upgrade the old gigabit machine but buy a newer machine. Any advice on which one? I'm wondering if I shouldn't look to a first gen G5 or if a Mirror Door one will do the trick. Again, I'm just trying to use Yahoo webmail, surf, use the newest iPhoto,MS Office, handle Leopard and hopefully one more OS generation. Any advice on a machine that would do that reasonably well?
