MSI GTX580 Lightning Review
As the GTX580 is clearly the fastest GPU by some margin we're really going to put it to the test by comparing it to Crossfire and twin-GPU cards.
3D Mark Vantage
Straight away the Lightning flexes its muscles by not only bludgeoning a reference overclocked card, but pushing the Crossfire setups hard too.
3D Mark 11
Understandably once we move away from the PhysX biased Vantage to 3D Mark 11 the Lightning drops away from the Crossfire cards, but still beats the 6870 CF setup. It's a country-mile ahead of its reference brother and that's the main thing.
