Is PCIe x1 Video card better than PCI?

I was shopping for a new video card and was reading that PCIe x1 ( not PCIe x16 ) wasn't really good when it comes to video cards. On the other hand, it's sort of known that PCIe is generally better than PCI right? I was wondering that even though PCIe x1 may lack in performance in compared to, say PCIe x12 or x16, is it still better than a good PCI card? Or does PCI out-perform PCIe x1? If you have any knowledge when it comes to these two types of video cards, I'd appreciate your help.



By the way, I'm trying to do a bit of gaming with the card I buy too, so keep that in mind.|||Technically yes a PCIe x1 card would be better than a PCI, due to bandwidth and the fact that all the PCI cards would be super old by now. For gaming however, i wouldnt even bother getting either. You shoud go PCIe x16 or not bother because no real gaming cards will come in x1, just low power ones.|||Maximum capacity of a PCI slot is around 533 MB/s.

Maximum capacity of a PCIe x 1 slot is around 250 MB/s.



Those numbers may seem to speak for themselves, but they are confusing. See, all PCIe x 1 slots are the same speed. But there are several variations in the speed of PCI. Depends on the manufacturer and when it was made. It could be as slow as 133 MB/s if it is older and running at 33Mhz.



But overall, you are not going to get great performance out of a PCI or PCIe x 1 card. At least not on newer games. If you aren't gonna play anything that came out after 2009, you should be fine. Anything newer, and you are better off upgrading to a newer mobo with at least a PCIe x 8 slot and newer protocols. You can probably get a newer card to run in your older board(if you have a good power supply that is), but it will be bottlenecked by the slower speeds of an older PCIe slot. Many computers are tricky, as they will often be compatible with older hardware, but will only run as fast as the slowest part.
