I’ve just about finished upgrading my PC now. The new 100 GB hard drive is in and working. (The old one is still in too, unfortunately. I can’t get it out. Long story.) The PCI modem is in too, as is the new video card. The video card is an MSI Ti 4200. It seems to be working well, although I haven’t tried anything that would really stress it yet.
Also, I’m getting used to having a CPU temp of 53 C or so. Apparently, that’s well within the margin of safety, even it is a lot hotter that my old setup.
