You’re welcome. Now, as I’m sure you know, comments about Moderator decisions belong in the Pit. I’m sure you’ll do better in placing such comments there in the future.
I’m not sure if there’s a craigslist or Bargain Finder or the like near the Duchy of Grand Fenwick, but I’d look in to a used PC if I were you. I just gave my parents an old PC of mine that’s twice as good as yours, and it was used when I bought it ~3 years ago. Around most offices, PCs like yours get thrown away.
Some people selling think their 5 year old PC is still worth $1500, but most have a reasonable if not under-valued price in mind; if money is tight (or you’re just a cheapskate on principle like me ), then it’s the way to go.
While you save up for your new computer and the fun of Civ 4 (with the Warlords expansion kit), you should be able to run Heroes of Might and Magic 3 on your old machine.
Both are turn-based games of skill, with easy to learn controls. A game lasts a decent time and you can soon pick up where you left off.
Now is not the right time to be buying a new computer. Wait until the summer when the mainstream DX10 graphics cards become available. Then get a cheap Dell with Vista. The trick is to get one of the machines they’re end-of-lifing.
