Gigabyte’s four-way CrossFire/SLI-supporting motherboard provides today’s test cards with all the performance they need, while opening up the possibility of future CrossFire scaling articles using some of today’s data.
Clock speed has often been our biggest bottleneck in achieving full graphics card performance. None of our games require more than three processing cores, yet Intel’s six-core Core i7-980X is already in the board and easily supports 4 GHz overclocked.
OCZ’s Z1000M provides over 88% efficiency across a very broad range of loads, at minimal noise.

This author’s argument against definitive noise measurements is that it’s almost impossible to remove background noise contamination from a running system. Yet, many readers insist that these measurements must be taken for relativity's sake. Using a “supersized” CPU air cooler that takes several minutes to warm up, the CPU fan has been temporarily disconnected during sound tests to get a somewhat-close approximation of each card’s true noise level.
