Crossfire on Cheap 775 Board

So, As i know there's little difference between x16-x4 VS x8-x8 Crossfire. But, I really wonder if there'll be any difference CF with 775 vs 1155 board and between cheap and expensive board?
Thanks :D

    nope as long as the gpu isn't too overpowered for the cpu, boards don't directly make a difference here.
  2. x16/x4 is a LOT slower than x8,x8, especially on S775. Years ago, Toms did an article on Crossfire performance, and the P35 chipset on S775 (x16/x4) was definitely not the way to go.

    Edit: There is, however, little difference between x16/x16 and x8/x8.
