Confused with win XP and Win 2000

I want to format pentium III with ATI 9200 PRO 128MBand it was not that to put an operating system, the computer is somewhat slow, but I wants one that is compatible with all kinds of programs. What do you recommend?

Greetings and thanks in advance!

I would recommend you windows xp

if it is slow put win 98, it is better than XP , win 98 will make it little faster.

hello ...

take a tour by the minimum requirements to install Windows XP to be safer ...

and then comment

greetings

But 98 is not compatible with existing programs!
