Better OS for DOS-based games

Just wanted an opinion on something regarding older games.  Would it be better to install Windows 98 or 95(as well as having Windows XP) on the computer and at start-up choose which OS to run.  Would this aid in playing and installing older, DOS-based games?  If it is better, could anyone please help me regarding the installation of 2 OS and how to make it so I can choose which OS to run at start-up.

Thanks.

No need for another OS. Or if you really wanted to...get another HD (or make a partition) and install DOS on it. Whenever you get the itch to play old school games just swith the boot options to that HD in the BIOS.

Try VDMSound too. And imo running old games with windows 98 is easier then running them in XP. But With dos box and VDMsound you can run most of them without problems.
