The guys at “TweakTown” have pushed SLI to the limits and built a system using 3 GTX285 cards and an overclocked cpu, and ran it through a full benchmarking suite. From their site:
Unlike the GTX 295, we can install three of the GTX 285 cards into a compatible system and what you essentially end up with is three cores. And while this is less cores than a Quad-SLI GTX 295 setup which only offers two cards but a grand total of four GPUs, the performance on a GTX 285 is superior to a single core on the GTX 295.
With the help of Inno3D, ASUS and GIGABYTE, today we’ll be having a look at how a Tri-SLI setup performs and what kind of performance improvements we get as we slot in not only a second card, but a third.
Their results? Amazing, but hardly worth the expense incurred. With issues ranging from the massive power requirements, extreme amount of Heat, heavily overclocked CPU, and three $400 video cards, it’s definately not for the faint-of-heart.
