PCI ,PCI express x1 slot uses?

[knk2009]

I am upgrading my graphics card to a sparkle gtx 560 ti on this coming Monday.

Altogether my motherboard has 1 C, 1 PCI and 2 PCI express x1 slots.

Will be using the PCI express x16 2.00 for my sparkle card but am very new to computers and would like to know what uses

there are for the PCI and the PCI express x1 slots?

Specifically wondering if I can use any of them to add an additional graphics card or feature to improve graphics even more or

if they can be used for extra fans or a sound card?

It won't improve graphics and no to anything over PCIe x1 like enterprise raid controllers.
