Crossfire PCI-E slots
Posted 24 April 2012 - 11:44 PM
Now i know the x4 will bottleneck a card, but i would like to know how much would it affect that second card if it was in the slave configuration in a crossfire. Any information would be nice, thanks in advance

Bandwidth bottlenecks do happen.

I'm probably looking at crossfiring a pair of 7850s, but I'm only gonna have one for about 6 month

16x/16x or 16/8x slots.

It seems to me the bottlenecking would be present, but the card would still give most of its performance. Is it still worth doing? No, imo. The loss of performance might be modest, but combine it with microstutter and it becomes non-worthwhile.
Just get a single Radeon HD 7970 instead.

Its only an x4 pci-e 2.0.
The crossfire idea is that i get one 7850 now with the money i saved up and then get another during black fridayish if they have any good deals. Otherwise i think a single 7850 is more than enough to play most of my games and won't set me back more than $260

The difference between 8x 8x and 16x 16x is only a few percent in performance.
And, instead of 1 7850, get 2 7770's.
