:pt1cable: Hi, i wanna know if i can crossfire 2 5770's on a mb with the second pci-express slot being 4x. And if its worth it, or if the x4 will limit the second card.

Thanks

Hey,
The 4X will reduce the scaling from the second card, but not so much that I wouldn't add it. There are a fair number of articles(some of them here) in regards to the diffrence from 4X, 8X, and 16X. I'm often surpised by how small the diffrence is between them. 2 5770's are a cheep way to get great performance, I just replaced mine with a single card solution, but I was very happy with the performance I was getting.
