Default Re: I change my mind about the GTX280

This notion that single GPU cards offer smoother overall framerates is hogwash. Stalker Clear Sky offers better performance (higher minimum framerate) on 4870 Crossfire as compared to a single 4870. At 1680x and maximum settings, a minimum of 22fps on Crossfire vs 13fps on a single 4870:

How "consistent" something is doesn't really matter when you have drops to 13fps.

The key component is the minimum framerate. This determines how smoothly a game plays. In my own tests I've found a large difference in minimum framerates between single/multi-GPU setups as well. Look at the difference in the minimum framerate on Oblivion between a single GPU and Crossfire:

Now which is going to be smoother? 28fps or 49fps?

And Mass Effect, a minimum of 31fps on a single GPU vs 54 in Crossfire:

And Call of Juarez.. the minimum more than doubles going from 29 --> 64:

None of these tests above are run at high resolutions, either. At higher resolutions, this is magnified even further since multi-GPU shines at those settings and a single GPU tanks.

I just don't understand this mindset that you and some others have by claiming a single GPU setup offers a better overall gaming experience. It's nonsense. If you have a setup that is running games at a minimum of 64fps vs. a setup that's running them at 29fps, you're going to have a much smoother gaming experience in multi-GPU.
