Which out of these 2 cards is best

[Jabbs]

As thread says after a new sound card which will give me best results, will be used mostly for gaming and with headphones for gaming i got it down too these 2

Creative Sound Blaster X-Fi Xtreme Music - Retail

Creative Sound Blaster Audigy 2 ZS Platinum Sound Card

They both roughly the same price just not sure which to get out of the two.
