- Should I be concerned about the "Check system health - VCore=2.05V" error message when booting the P3-600?
My guess is the 'Check system health' message doesn't have anything to do with the Vcore voltage, despite the confusing way it's presented. I've had a couple Gigabyte boards display the same message and it always turned out to be related to either the lack of a -5V rail or a missing/too low CPU fan RPM. Go into the BIOS and find the section that displays detected voltages, temperatures and fan RPMs (should be something like 'hardware monitor' or perhaps under 'chipset features'). You should be easily able to spot which detected value is going to be out of range or not present. If the BIOS allows it, disable monitoring of that particular value. If you can't disable it, try upgrading or downgrading your BIOS, sometimes later or earlier versions add the option to disable monitoring of certain values.
As for the build itself, besides the other recommendations others have already mentioned, I would seriously consider upgrading the CPU to something faster, like a 800-1000+ MHz Coppermine. The Voodoo 3 can scale up to those CPU speeds in many games, at least at resolutions up to 800x600, so a 600 Katmai would still be bottlenecking it regularly there. If you intend to play at 1024x768 or higher, then CPU bottlenecks will not be a concern.
As for the 3rd build (XP), I would honestly just replace the whole thing. The CPU is pretty weak for anything but early XP era games, likewise the 1 GB of RAM, the SB Live fits more into a Win98 build and should be replaced by an Audigy 1/2 or X-Fi for EAX4/5 support. And then there's the weakest part, the video card. The 7300 LE is quite simply too weak for XP games, I'm not sure it would even beat a geforce 4. I strongly recommend scrapping that whole build and replacing it with a Core2 one. Those are dirt cheap to get, you can find a bundle of motherboard + CPU + 2GB of DDR2 (or more) for like $10-20. Add a cheap low tier DX10 GPU, can even be something as low as a geforce 8600 for another $10 (but stay away from absolute trash like geforces 8500/8400/9500/9400/210) and you have a $20-30 XP system that will run absolute circles around your current one.
