PowerMac G5 1.8Ghz, 1.5GB RAM with Radeon 9800 Pro 128MB (Mac version; from factory as I paid almost $600 extra for the 9800 when I bought the G5 in 2003.)

MorphOS 3.7 - Runs generally fine; Occasional lockups if left on over night or so but otherwise it seems to work fine. Finds only about 960-980MB RAM.

MorphOS 3.8 - Extremely slow when booting from the CD; Fails to find any of my harddrives. Did not attempt installing it at this time (ie. mounting the disk from OS 3.7 and manually installing it). Finds around 1470-1480 MB RAM.

Mac OS X 10.5 - Rock stable (Before I installed MorphOS about a year ago, the machine been running 24/7 for 3 years), I've occasionally had it running OS X for some weeks a time still without any issues. Apple Hardware Test reports no errors either.
