Hi everyone,

I finished building my first pc about six months ago, and really enjoyed it. So much so, that I want to do it again! But since I don't have a money tree, I though I could scratch this itch by adding some bells and whistles onto my rig.

Enter PCI slots. x1, x4, x8, M.2... Officially confused! Could someone please give me a list of what kinds of components could go in these various places and perhaps some recommendations on their usefulness? Gaming is the main purpose here.

Any feedback is appreciated!

Well, there is some confusion here, but not a ton.

PCI x1. x4. and x8 slots are typically found on the motherboard and take in parts like SSD's, sound cards, wireless (wifi) cards, extra USB ports (3.0, type C, 3.1 etc), and much more.

M.2 ports are for 2 things depending on the technology. Yours is probably for storage but some for smaller platforms hold wifi or network cards for wireless computing.
Typically in desktops they are used to put in M.2 style SSD's which are very fast.

There are two types of M.2 ports. PCI-E based and SATA based. PCI-E is much faster but is a recent technology and most boards do not use it yet. It comes in x1, x4, and x8 variants. SATA M.2 is more likely and uses the same technology as a standard sata port to transfer data.
