Got it installed on a Pentium 4 2.4Ghz with HT and 1 GB of RAM. WEI Scores: Processor: 3.4 RAM: 4.4 Graphics: 2.1 Gaming Graphics: 2.7 Primary Hard Disk: 5.3 Seems usable. Certainly not a speed demon, little surprised the RAM and HD scored so high because it seems when there is a noticeable amount of lag it is when the HD is churning away pretty hard. Suppose thats just the lack of RAM. But I'm not going to be upgrading the RAM in this thing anyway (old ram is way too expensive) Was disappointed on first boot that neither the graphics card (nvidia 6200) nor the audio (some c-media chipset) were not auto detected. So on boot I had 2 resolutions to choose from and no audio. Fortunately this machine also boots into PC-BSD and Windows 7, so I was able to go to the other hard drive and get the nvidia drivers from <Win7Drive>:\nvidia and then I told Device Manager to look in <Win7Drive>:\Windows\system32 to find the audio driver. So I have decent video and sound now. I moved the pagefile to the other physical hard drive and set its min and max size to be the same. That should help a bit with the disk churning and responsiveness. Since it won't be read writing information to the same drive its read writing swap memory on.
