What's the difference between these two sound cards

What's the difference between these two sound cards?

SB0770 | Creative Sound Blaster X-Fi Xtreme 7.1
SuperBiiz.com - Creative Labs Sound Blaster X-Fi Xtreme Audio 7.1 24-bit PCI Sound Card, Retail

They are both Creative Labs Sound Blaster X-Fi Xtreme Audio 7.1 24-bit PCI Sound Cards.

But i noticed the 1st card has 7 plug-in jacks (2 of which on the right-hand side i don't even recognize) vs the 2nd card has only 4 plug-in jacks

I'm trying to decide which card to get.

thanks in advance
