Hey guys, first post. I'm not smart at all about computers, and i don't feel like paying someone just to tell me whether i have a AGP x8 slot, or PCI-E x16 slots... my motherboard is a Board: WinFast C51MCP51 FAB1.0
And it looks like it has both kind of slots. There are a total of four slots, the one highest is greyish, and the three lower ones are white? So, which do i have? An answer wold be great, thanks.
 
Ok as far as i can tell, i have 3 white Pci slots, and my black one looks PCI-E But I'm not sure, It's sort of skinny, and has a thingy sticking out of the end of it, the thing that PCI slots don't have on the end 😀
So is my black a PCI-E?

Edit: it has the things sticking out of the ends, like these. http://www.pcstats.com/articleview.cfm?articleid=2487&page=2

The blue things look like what my black is, but my black looks a bit skinnier.
 
If the GPU slot you're concerned with has the small sector closer to where the monitor cable is connected, then it is PCI-E. Both AGP & PCI have the small sector on the opposite end. If you post a picture of the slot on your mobo, it would be much easier to be certain.
 
Hopefully this helps...

That's a PCI-E x16 slot. Yours would likely be a 1.0, though. PCI-E slots are backward/forward compatible, but limited to the technology of the older hardware. What this means is, if your mobo has a slot that looks just like the one in the pic you linked, then it is indeed a PCI-E slot.

Furthermore, since your mobo is 10 years old, then the PCI-E slot is likely version 1.0. You can install a new PCI-E interface GPU into this slot, and the GPU will work, but the max thoughput of 250 MB/s.
