Thanks everyone, for all the feedback and suggestions. I will try taking the power off the optical drive connectors next, and see what happens. I have the molex for the 9800 running off the hard drive connector for the drive cage under the optical bay, where I have two SCSI drives (RAID).
As far as power goes in general, I *do* have four drives. But I have one empty PCI slot. So I'm not sure if I'm maxing out power or not. Regarding heat as the issue, I'm not so sure. According to iStat, the processor temps hover around 49 degrees C. I've been checking it from time to time, sometimes after doing more processor-intensive tasks, and I've never seen a temp over 50 C. It seems to me that that's an acceptable temp for the processor. Thanks! Rob J.
