Thanks for all the input! I did some serious testing and benchmarking when I got the dual 1.8 GHz G4 upgrade, and I never got it to run reliably beyond 1.6 GHz. I benchmarked at 1.53 GHz using Geekbench (CPU and memory tess), and it was 27% faster than the dual 1 GHz MDD under Tiger, 19% faster under Leopard. 1.6 GHz is just 4.5% faster than 1.53 GHz, so a 1.25 GHz MDD would probably provide equal performance overall under Leopard, although it would take a 1.42 GHz MDD/FW800 to match Tiger performance.
<http://lowendmac.com/reviews/09rev/giga-1.8-ghz-dual.html> The ideal would be a pair of 1.42 GHz FireWire 800 models with maximum RAM. Based on all the feedback, I'm leaning toward another Radeon 9000 Pro for the MDD and bumping RAM in the DA from 1.25 MB to 1.5 MB. I may also look for used 1.25 GHz and 1.42 GHz models. Craigslist can have some great deals! (I got my 22" Cinema Display with a Quicksilver 867 MHz for $175 through Craigslist, then sold the Quicksilver for $100. I love this display!) Thanks again!
