Older games on new computer

Ok I'm currently looking to build a computer that will be something like this:

Vista 64bit

750i FTW

Q6600 @ 3.2

8800gts 512mb x2 in SLI

4gb DDR2

Now my question is will I be able to play older games on this rig as well as new ones? As I have only recently looked into getting into computer gaming I have missed many what you may consider "classic" games. I have heard there are compatibility issues with Vista and older games, as well as with newer graphics cards. Will installing XP on second HDD fix most of the problems? Will there be any issues with the hardware?

The games I'm talking about are pre 00's

keep your old harddrive and just boot it up whenever you want to play :)DivergeUnify

So basically dualbooting a second harddrive with XP on it will fix any problems? Because I don't really want to have to build a second computer.

I have my old Xp drive, but i was never able to set up the boot menu, so whenever i want to load it i have to press f8 and select which hardrive to boot from :(

But i have mechwarrior 2 on it so its worth it :P
