x16 or 16 lane cards are typical for graphics cards. If you have concerns when you are ready to buy we can look at the specific motherboard product you are considering.

If you are waiting for motherboards with usb 3 and 6 G/bit sata then it isn't likely you are going to need to worry about this. The boards will have the latest spec pci-express slots. ]]> http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23299764 Fri, 06 Nov 2009 00:31:54 EDT http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23299168 http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23299168 Thu, 05 Nov 2009 21:56:47 EDT http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23294597
So you might ask why add more lanes or higher bandwidth lanes? So the capacity is there when newer generation graphics cards need it. At the present time the pci-express version doesn't matter because the v 1.0 bus is capable of handling the traffic. ]]> http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23294597 Thu, 05 Nov 2009 03:27:22 EDT http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23294582
Because present cards aren't saturating the bus yet. In fact very few present cards, except possibly the highest end cards, are even much limited by x8 rather than x16 v1.0. The x16, x8 x4 is the number of lanes. Each lane is capable of about 250MB/s. with v 1.0]]> http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23294582 Thu, 05 Nov 2009 03:27:14 EDT http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23293788 said by asdfdfdfdfdf :

"What about all of us poor SOBs that have motherboards that only have PCI Express 16x slots?"

You don't need to worry about this.
There is no problem running a 2.0 card in a v1.0 slot. In fact there is no performance loss for single cards either.

If there is an upgrade you are contemplating give us more detail about what you are trying to accomplish.
I was wondering about this the other day too since I havent kept track on the PCIe phenomenon.

Just wondering how there would not be a performance issue if you're running a 16x 2.0 card in a 1.0 slot or if you're running a 16 x 3.0 in a 2.0 slot? And what about this x16, x8, x4 that are shown in the specs of various mobo manufacturers?]]> http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23293788 Wed, 04 Nov 2009 22:26:17 EDT http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23278544

a 1 lane PCIe version 1.0 card has a capacity of 250 MB/sec
a 1 lane PCIe version 2.0 card has a capacity of 500 MB/sec

when PCIe v 3.0 comes out, a 1 lane card will do 1 GB/sec

a 1 lane card is the one with the very small PCIe connector, and a 16 lane card naturally is the card with the longest connector.

a 16x version 1.0 card can do 1 GB/sec
a 16x version 2.0 card can do 8 GB/sec

a 16x version 3.0 card will do 16 GB/sec]]> http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23278080 Mon, 02 Nov 2009 10:36:34 EDT http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23277947 »www.newegg.com/Product/Product.a···13131222

your welcome.]]> http://www.dslreports.com/forum/Re-PCI-Express-16x-vs-PCI-Express-16x-20-23277921 Mon, 02 Nov 2009 10:07:26 EDT http://www.dslreports.com/forum/PCI-Express-16x-vs-PCI-Express-16x-20-23277843
So what is PCI Express 16x 2.0? What is the difference between that and the old PCI Express 16x standard? What about all of us poor SOBs that have motherboards that only have PCI Express 16x slots? What do we do?

God, I can't believe how fast this stuff changes. Don't read anything new or pay attention to the trends for six months and you can quickly fall behind.
