I've been looking around as always at stuff, and I've noticed that some motherboards say that they have two PCI x16 slots, but some say the blue runs @x16, and the black runs @x4... I'm not sure whether I need both of the slots, but I'd like to know if it would kill the chance to SLI some cards, or what?

For example:

Those two slots are for SLI or Crossfire. A lot of the older boards (and newer ones) have one of the slots clocked down to a slower speed. This will slow down the graphics card a bit especially one running at only 4X. I remember reading 8X is alright, but you should spend the extra money and get a board that has both slots X16.

So any PCIex16 card will fit in it. It's just a PCIex16 slot underclocked.

Two x16 sized slots where one is only x4 electrical is a common setup on P965 and P35 chipsets. You can stick two graphics cards in them, but the x4 slot will limit performance on very high-end cards. Note also that neither the P965 nor the P35 chipset supports SLI, they only do Crossfire.
