Performance - dGPU GTX 780 SLI Gaming

So on this page we'll have a peek at Multi-GPU Gaming as well. Overall the X79 / 4820K platform 'could' be notch faster with more PCIE-express lanes over Z87 / 4770K. It however is not as simple as it seems. Below we have installed two GeForce GTX 780 card in 2-way SLI mode and will start to see if the platform makes a difference at all. We'll compare the Core i7 4820K, the Core i7 4770K and then Core i7 4960X.

So in the test above we apply medium quality settings. This will tremendously boost overall performance as you can see, and that will disclose witch processor is faster in performance. And yeah, weirdly as it really is, the 4820K is a tiny notch slower. But all tests in this review already have shown that behaviour.

However will that change once we make the GPUs render in Ultra image quality modes where PCIe bus lane behaviour will become more important ? Well if you look above you'll notice that it somehow does make a difference.

We do the same with BioShock, above medium quality settings, again the 4820K stays behind a little. 

But unfortunately with BioShock once we enable rather extreme Ultra Image quality settings and DDOF, the X79 platform with 4820K stays behind in performance a little.

This is the weird thing to see and measure with a Quad-Core Ivy Bridge-E CPu, as on paper it should be a hint faster compared to a 4770K. Now do bare in mind that at 1080P we are talking about 2-3% differences overall. Nothing you'd ever notice.
