Results: 3D Mark Fire Strike
The latest benchmark from Futuremark can certainly hammer on the latest video cards. I run the tests at the standard setting so we can set a good baseline for how a card SHOULD perform. AMD and NVIDIA work very hard to tune their products to these benchmarks, so this should be a measure of theoretical performance in a controlled situation.
The GTX 760 ITX performs slightly better than the overclocked Asus R9 270X, but quite a bit slower than the more expensive 280X (which is also overclocked out of the box). We can squint a bit and figure out that a R9 280 would outperform the GTX 760 ITX and score around 7000 points.
