Conclusion
First of all lets talk about prices. Let's consider that
the two GTX 760 DirectCU II OC together cost 399 Euro. Compare that to the
432 Euro you'd have to pay for the cheapest reference AMD Radeon R9 290X we can
find. Therefore this one high-end card is is about 10 percent more than the
two mid-range models.
To dive a bit deeper into the results, we start with performance differences in
3DMark graphics score where we see that the SLI of two GTX 760 is between 5 and 12 percent faster
than the AMD Radeon R9 290X. In the next theoretical test we ran, Unigine Heaven,
we see that the two 760's are on average 7 percent quicker than the AMD Radeon R9 290X.
In case of games it turns out that for example in Dirt Showdown the
AMD Radeon R9 290X is about 16 percent quicker than the two smaller cards in SLI. A
closer look at Crysis 3 shows the other end of the scale, where
the two GTX 760 score 48 percent better than the single AMD Radeon R9 290X. In case of ultra high resolutions we would see the two smaller cards lack behind, since they features less video memory.
Overall the two GTX 760 cards are performing really well and there is no doubt
the two of them are seriously quick, actually, on average they're 12 pecent quicker than one AMD Radeon R9 290X. Last but no least there is
the power consumption which is 12 percent higher than with one single AMD Radeon R9 290X.
If you're actually thinking
about buying two GTX 760's make sure you go for models with 4 Gigabyte VRAM
otherwise the AMD Radeon R9 290X will be quicker playing games at ultra high resolutions. When it
comes to price/performance, than the two GTX 760 in SLI are simply great. Since
drivers are meanwhile quite well optimized for SLI, almost any new game is
supported with well balanced profiles.
