Advantages of crossfiring...

post #1 of 8
Thread Starter 
Just installed a 6950,
after reading up on crossfiring was debating adding another
card but I don't see that much support for the platform, not to mention
I see some of you CF guys experiencing problems with CF setups more
than single-card

Beyond that, I would just wait on the next-gen cards and see what's up,
but CF seems like a cool idea

PS Is my CPU up to the task?

Basically crossfire give better performance. If your lucky, you will get an 80% performance boost by adding another cards. However, they can be unstable and have driver issues with certain games. If you are using a 1920x1080 monitor, I would stay stick with one 6950. It will be more stable to you and that card will be able to handle most modern games on max settings. Especially if you unlock it to a 6970. With that being said, if you want to be future proof or you plan on adding more monitors, it might be worth it to crossfire. The 6000 series has made many improvements for crossfire and scaling is much better than the 5000 series.

I have had crossfired 4890s and 5850s....never had a issue with either setup...

The 6900 series scales really well...usually in the mid to high 90s in most cases..

I say go for it...

I absolutely love my 6870 crossfire setup. The difference between the single to xfire was unbelievable.

This is my first foray into AMD cards and so far, not one iota of problem with my CF 6950 ! I think those CF issues are old stories. I went from about 40 FPS in heaven benchmark to 80 FPS with stock clock. That tells me close to 100% scalling in crossfire. Right now, I am playing dragon age 2 and it plays so smoooth. I can tell you this much - I do not regret going CF - loving every moment of it. And you will too. If you got the bucks, go for it.
And look at me - I am still rolling 1680 X 1050. Now that's overkill !! (waiting for the tax money)

EDIT: If you do go CF, make sure to download the CF profiles from AMD website. The make a lot of difference.

6xxx series cards scale incredibly well, I've seen almost up to 100% scaling with my 6850's.
