We waited and waited. Eventually after somewhat of a delay nVidia launched their Fermi range of cards to much excitement from all of us. Or at least it was excitement until we realised that they had been reduced in performance in a vain attempt to get them to remain remotely cool, but even then they were woefully noisy and hot. A pair of GTX480s in SLI gave out a similar amount of heat to an exploding star, and about the same noise.nVidia secretly went back to their labs and greatly revised the Fermi 100, and here it is. Much sooner than any of us expected we have the GTX580. This comes hot on the heels of the recently released AMD 6-series cards and so undercuts AMDs own high-end graphics package, the HD6990. As this is the first time for a while that nVidia have hit the market before the equal AMD card we can't wait to see how the gauntlet has been thrown down.nVidia claim this is everything the GTX480 should have been, with all the hardware tricks and tweaks turned on and a greatly revised cooling solution. They go so far as to call it the best graphics card on the market. Of course claims and reality don't always meet.Let's have a look at the specifications and see if this is a revolution or purely an evolution.
