CrossfireX at x4 vs x8 - Page 2

post #11 of 29
there is hardly any difference between crossfire on dual 4x and dual 8x and dual 16x idk why everyone says that they wont crossfire under 8x since there is very little performance drop when i find the website i will edit my post

EDIT: found the link http://www.hardocp.com/article/2010/...16x16_vs_x4x4/

x4 makes a difference, x8 not really, x16 is optimal

Like mw2 where it drops almost 90fps

Its not worth knowing you will get worse performance, just get the x16/x8

Maybe on avg..
But there are times when it will be more, and noticeable.
Take the Modern warfare from that Toms link as an example.

The point is there's no reason to chance it.

I've ran 16/4x vs 8/8x and do not recommend it, performance drops, and the gpu usage on the 4x card is always 10-20% less than the 16x card.

My opinion is, if you are going for a new build or mobo anyway, and it's in the same price range, 8x/8x is obviously better. But if you already have a 16x/4x board, there really isn't a whole lot of reason to upgrade the mobo for the small amount of performance it offers.
