Just a tad confused, would appreciate an answer.
no. PCI-e 2.0 has double the bandwidth of PCI-e 1.1. Both of these protocols exist in a x1, x2, x4, x8, x16 variant. 2.0 is backwards compatible, so a 2.0 device will work in a 1.1 mobo and a 1.1 device in a 2.0 mobo. Today's GPUs hardly even fill up the bandwidth of a 1.1 x8 port, so practially you don't need to worry about it
once upon a midnight dreary, while i pron surfed, weak and weary, over many a strange and spurious site of ' hot xxx galore'. While i clicked my fav'rite bookmark, suddenly there came a warning, and my heart was filled with mourning, mourning for my dear amour, " 'Tis not possible!", i muttered, " give me back my free hardcore!"..... quoth the server, 404.
PCI 2.0 slots are backwards compatable with PCI x16 slots. So I you can use a 2.0 card in a x16 slot and vice versa.
Thanks all.
Yeah, this confused me at first too, a little Googling did the trick.
