Quote: "Now I'm also thinking I may need two separite PCs, one for older DOS games and another for late 90's - 2000 type games, which are slightly more demanding."
a pentium 1/2 with win 98 is good for dos games. Older 90s//early 2000 games will run on any pentium 4 mashine with windows xp or win 2000. Both of thesse are realativley cheap. depending on where you live, you might even find these mashines at your local dump or recycling center. i found my first p133 laptop in my local dump when i lived in the states. i found tons of comuter crap even pentium 4s at a local dump in US.
dont hate people who rip you off,cheat and get away with it, learn from them
