my motherboard says it can hold PCI,PCI Express X1,PCI Express X16.but the ones on the website says 2.0 x 16,2.1 x 16.im new to buying a pcie video cards, i've only put in pci cards.so as long as it says pcie it should work?which one do i need to get?thanks|||You are confused on several things.
First of all, PCI and PCIExpress are COMPLETELY DIFFERENT things and are UTTERLY incompatible, despite the similarity in name. Don't EVER buy a PCI video card. You should be buying a PCIExpress 16x video card.
Second, you are confusing bus lane width with the version number. The "x16" and "x1" describes how wide the number of data lanes the PCIExpress slot has. Video cards use PCIExpress 16x. The 1.0, 2.0, 2.1 describes the specifications version of a PCIExpress card or slot. ALL PCIEXPRESS SPEC VERSIONS ARE COMPATIBLE WITH EACH OTHER. It will just run your system at the lowest spec version's speeds if your vid card and mobo slot are different spec versions.
Buy a PCIExpress 16x video card. Any of those PCIExpress 16x video cards will work on your motherboard's PCIExpress 16x slot, doesn't matter what spec versions your card or slot are.|||Get a PCI-E x16. Doesn’t really matter what version. You should get 2.0 or 2.1 if you have the option. PCI is different than PCI-E, so be careful not to mix em up :)
The x16 part defines how ‘wide’ the port is. x16 means it has 16 ‘lanes’. Just about any graphics card will be x16.
2.0 and 2.1 are the version of the port. 2.0 is like 1.0 except it has much more throughput for the same number of lanes. If you have a 1.0 port, you can install a 2.0 or 2.1 card, but it’s possible you won’t be able to use the card to its fullest potential (Good luck finding or affording a card this fast...). 2.1 is the same as 2.0 except it supports new managment and support systems—no performance differences—and also backwards compatible with 2.0 and 1.0.
