580 lightning OC vs 6970 OC?

post #1 of 64
Thread Starter 
I know the 580 lightning is a great OC'er but does it OC well enough to justify its pricetag as compared to a 6970 xfire setup?confused.gif

Xfire 6970 setup vs one 580? I believe the answer is two 6970s win that.

Agreed ant. 6970's in X are the better performers

Yea, the 6970s would destroy a single 580. But if you went with two 580s....

The lightning seems like an absolutely stellar card, its just that all the review sites seem to think that the 6970xfire is right up under a 580SLI setup, just trying to figure out if the OC potential of these cards could increase the bang4buck over the reference.

I think with the price you pay for 2xGTX 580 you can buy 3xHD6970 but to answer OP's question, you're better off with 2xHD6970. Even if some games don't make use of the second card you still get a solid performance with a single GPU.

From what I see the Lightning is pretty much the equivalent of the SOC series from Gigabyte which means potential for high overclock at low voltages, better temps and noise.

The OC limit for most Fermi GPUs is 900MHz, the Lightning will most likely also stumble at that.

Unless you're talking about the 3GB version which are even more expensive the 6970s in CFX is a much better choice because of the increased VRAM. At resolutions above 1920x1080 where these options are practical it's very possible to use up the 1.5GB framebuffer the 580s have. Not only that, but the 6970s scale better and are much cheaper.

580s are pretty fail.

At 2560x1600 the 6970s beat the 580s.

It keeps up with or beats the 3GB version, too.
