PCIE 2.0 x16/x4 crossfire - Page 2

post #11 of 15
The loss will be minimal at best, I went from 16x/4x to 16x/16x on a CHIV and at most I gained like 200 points in Vantage (which relates to pretty much nothing in terms of real world performance). That was with 5850s so you wont have any issues with 6850s.

These scenarios are very different. Everyone always mentions this review, but the problem with it is that the "feel" is much different for crossfire in x8,x8 and x16,x4. I've done a review on this, which has been buried, but I found that not only did x8,x8 give you more performance, it also felt much, much smoother. It's was pretty much like the difference between 30fps and 60fps in a game.

@OP if you want to do crossfire, get a proper board that supports x8,x8.

What are your thoughts on 16x / 4x except with the 4x being a physX card instead of a regular card? My new mobo has 8x/8x/4x and I want to toss the phyX card in the 4x slot instead of the 2nd slot to make room since I'm watercooling. With the second slot being empty, it would become 16x / 4x

On this subject I was trying to figure out if there was a board with true 16x CF\\SLI support? Its hard to find an exact answer for this and its driving me crazy with all the x4, x8, x16 discussions out there. Any ideas?

So far I think I found one "GIGABYTE GA-Z68X-UD7-B3" and its too expensive.

16x/16x will give you no benefit over 8x/8x or 16x/8x.

Just find a good board that has 8x/8x cf or better. there are tons of them
