PCI slot noob question

I have a question that needs an answer so that I can ask an opinion question later.

So here goes with my noob question. How can I tell what kind of PCI slot I have? I have a DFI motherboard that is a few years old and want to replace with on-board sound with a new sound card (this is the opinion question). However, before I can even think about asking which 5.1 sound card would be the best for under $50, I have to know what sort of PCI slot I have. I know for certain that I don't have PCI express (i know I should... but hey, I'm poor).

IF you're feeling really helpful and caring, you could suggest the best sub-50 buck soundcards for any/all PCI slots that would support 5.1 sound.

Thanks.

also some are red or orange.

agp i mean

pci

agp

isa

pci express (the black highlighted one is pci express 16x you dont have it just for show)

Just to give you a hint...
dfi uses different colors on there boards ranging from black - floressent orange to other very bright colors....

yeah i know. different manufactures, different brands.

thats why i posted to mr. familly, and he knows too

edit; in pci-e ive only seen blue and black.
but dont really remember or pay attention to colors.

Well it was for future reference.... ISA i recently worked on a scoreboard controller computer that was run from an isa card.

pci is mostly white
pci-e and agp can be almost any coloer.

thats probably what i should have said

cool, never experienced a dfi.
heard they are good overclockers.

most AGP are brown who knows that all I know

PCI white or creamy

PCI-Express black or blue in most cases. I saw oranges too and baby blue

Hahahahaha! Who Knows!

BTW, how many more posts do I need to become nimble nickle?
