Shows that PCIE 2.0 x16 and PCIE 3.0 x8 is still no bottleneck for a top gpu.

Awesome data, shows that the new external GPU boxes coming out at effectively PCIe 3.0 4x via Thunderbolt or USB-C should be only very lightly bottlenecked at worst

Nice, thanks for posting this.

I always like these articles, nice to see an updated one.

Maybe some min and max fps would be nice too.

Agreed.

I'm actually happy to see this. I shelved my mega gaming pc build for now as the hardware still somehow didn't justify the expense. I'm going to a 1070 strix on an old p67a ud7 with an overclocked 2600k on it and it seems that the pci 2.0 x16 doesn't really slow down the gaming experience at all. It's incredible.

Good idea! The 2600K overclocked can still almost handle anything you throw at it, what a value that CPU was/still is!

Wrong, the 2600K suffers massively lower minimum FPS in many games, when coupled with good graphics cards (1070 or higher), compared to a highly clocked Broadwell-E/Skylake/Kabylake.

You may be thinking about the 2500k - where this is undoubtedly true. The 2600k holds up a lot better with the 8 threads.

Nope, OC the 2600K to 4+Ghz and it will perform almost identically to the higher end Haswell/Skylake stock parts. The 2600K can still be used for high end gaming.

I love this data. Though, it does make me question what can be inferred by some games having very limited differences in their scaling performance? Is that optimization of the engine, lower memory filling requirements of the game, or possibly some superficial bottle-necking? I find that curious for some of those games tested.

Take a look at COD: Black Ops 3 for example:
