if i were to play a high end game such as half-life 2 or doom 3, would i a cd drive from an old windows 98 computer work, or would i have to get a faster speed of cd drive?
Even if it's a slower CD drive, it will still work. It'll just take longer to install all the files from the CD - it shouldn't affect game performace at all.
How about 5 times? Yes, your old CD-ROM will work in your new computer. To make sure, double check the system requirements of the game (usually they say how fast CD-ROM to use), just in case if the game runs off of the CD.
No, nothing was added. It was the same answer worded differently. I'm not yelling at you or anything, I just thought it was pretty redundant. As for me doing it, I don't answer a question that has already been answered by somebody else (unless the answer is wrong or incomplete, of course).
