Power Overwhelming

As the graphs show, 768 CUDA cores working in tandem is a fearsome combination, which is exactly what we expected. Scaling performance was also inline with our expectations, as we noted significant increases in performance. On newer titles such as Battlefield Bad Company 2 and S.T.A.L.K.E.R.: Call of Pripyat, the gain an additional GeForce GTX 560 Ti provides can be as much as 82%. Also, we noticed that on games such as Dawn of War 2 and Far Cry 2, our CPU just couldn’t keep up with the enormous amount of graphics horsepower that was at its disposal. We can't wait to transition to the next heavyweight CPU coming in the months ahead as overclocking is just a stopgap measure and not reflective of what most people can achieve or use as a base as reference.

So as we've found, a 2-way SLI configuration consisting of two GeForce GTX 560 Ti is certainly a formidable one. However, it does have a few drawbacks. Fortunately, noise wasn’t one of them as even the reference cooler is fairly quiet, but power consumption certainly is. As seen in our graphs, the power draw of the GeForce GTX 560 Ti is uncharacteristically high, and with two in an SLI configuration, matters get worse. In our tests, our highest sustained reading was a considerable 422W, which means a solid PSU rated for at least 650W or 700W (to be safer) would be needed. And that's assuming the system isn't loaded with many other add-ons.

Also, one also has to take into account the amount of heat produced. With a single reference GeForce GTX 560 Ti card, we recorded operating temperatures to be around 70 degrees Celsius, but when placed in a 2-way SLI configuration, operating temperatures increased to 74 degrees Celsius per card. And mind you, two cards running in excess of 70 degrees Celsisus produces quite a fair amount of heat. Needless to say, a casing with adequate ventilation to expel excess heat is crucial as built up heat within the chassis can shorten the lifespan of components, or worse, even damage them.

In closing, two GeForce GTX 560 Ti cards in a 2-way SLI configuration is a formidable combination. What this really means is that users can get themselves a GTX 560 Ti and rest assure that in future, more graphics power can be gained simply by adding an additional card to the mix. A side note for this to materialize is that one should already have an SLI capable board with decent bandwidth per PEG slot.
