Is it worth upgrading from a Audigy 2 platinum to a X-FI platinum? or should i just stick with the audigy 2 platinum.

What speakers do you have?

I went from an Audigy 2 to my current X-Fi FPS http://www.newegg.com/product/prod [...] 6829102189 and I can tell the difference on my Klipsch speakers in both games and music. It depends how much sound quality matters to you.

I have creative 5.1 speaker system.

In my opinion, no. You probably won't hear much (if any) difference going from an Audigy2 to an X-Fi. The Audigy2 is still a very good card. I have an Audigy2 ZS in my old computer but when I built my new one, I went with the X-Fi just because it was the latest and greatest and I didn't notice any difference at all except the X-Fi drivers were more fussy.

It's really all about the speakers attached that is where you will get the difference. My 5+ year old Cambridge Megaworks 550 5.1 speakers are still kickin' and work great for me but might have a different opinion if I had a set of 7.1 speakers.

thanks and thats the same speak set i have i think i have had mine about the same time to think i got them in dec of 2002.
Thanks for the advice.
My brother just called me hes coming down for easter and he has an extra X-FI platinum card says he will sell it to me for $100(canadian). Not a bad deal, tempting.
