look at mb spec again closely.. a lot of mb now in the z77 and x68 are doing one video slot at 16x and the other at 4x.
Yeah, I noticed that. Do you recommend spending $20 more to get a mb that can do 8x by 8x with 2 video cards? Or would it be better to just invest that money in a new GPU when the HD 6950 becomes outdated? (I don't plan on doing crossfire in the near future.)
