Is any one running 7950s in Crossfire or Trifire yet - Page 2

post #11 of 15
If you just want stock 7970 performance then sure, get a 7950 and overclock it. But if you want the MOST performance then stick with the 7970 as once you OC it the 7950 can't catch it. If it could I would run 4 of them lol biggrin.gif

You should really take a look at this if you are considering going for a tri fire solution:

See the bottom graph with Crossfire 6970. Imagine what it would be with three GPU eek.gif
This is the dark side of multi-gpu, at high FPS you may not see much difference, but as soon you get longer rendering time, the stuttering be more and more noticeable.

Pretty sure triple and quad GPU setups have LESS microstutter than dual cards.

Doesn't make much sense... We don't even know what is their axis. Could be FPS / time ?? doesn't take much more than 10-20 ms to render a frame!
It is logic there is more stutter. Every GPU have to be synchronised so they wait on others to finish...

I just thought since there are more GPUs, the waiting time between rendering is diminished.

the 6870 Trifire is perfect example of Microstutter Elimination the third card stabilizes the Synch between the other two GPU's but also provide 25% more performance in the end, unfortunantly if 6870 quadfire is done the 4th GPU becomes hectic and causes alot more stutter then that of the 2 gpu solution with no stabilizing.
