What's the difference between 2.0 and x16?

Do I need something different to be able to use a 2.0 card?

the 2.0 socket can provide more power through the mobo, thats about the only practical difference. also the spec is backward compatible with pci - e 1.x.

so if I buy a card that says "PCI-E 2.0" it will still work in my x16 slot?

Likewise, you can use a card that isnt PCIe 2.0, in a PCIe 2.0 slot

@ djcoolmasterx

 

I've noticed the posts dates, I just had to ask this, because I'm interested. I don't care that those are 2 yrs old posts ... maybe I'll get some useful replies. Why don't you just shut (tf) up if you don't have anything really helpful to say or something else to ask ? I bet you'll answer "Make me!" :) as childish and useless as your first post. On some other respectable forums your useless post would be considered as SPAM :D
And why you have to scream at me (CAPS LOCK) ... ? Can't you talk normal, or you're used to talk like this on a regular basis at home aswel??? Take a chill pill :sol:

 

Pfff ... lol :pt1cable:

A single gpu 2.0 card on a 1.1 board? No.

PCI-E 2.0 is x16 as well, the difference is that the theoretical bandwidth is twice as high per lane compared to 1.1. Sounds a lot, but the great majority of the cards today (if not all) perform the same with 1.1 as with 2.0.

so just to be clear.
a pcie2.0 card will work in a x16 mobo slot

so will a 2.0 card in a x16 slot have lesser performance then a non 2.0 card in a x16 slot?
