Good Point actually.
The 970 autoboosts it's clocks the cooler it is. So more than likely one case has better cooling than the other.
Do you expect 20 games benchmarked over all those configurations in the same time frame. I'll drop the guy a mail and tell him to pull his finger out of his ass.

Same drivers too? It's not uncommon for Nvidia to release a performance boosting update for a newer game.
Also a game running on a different patch, optimization etc.
If all that is the same, the temperature theory isn't too bad actually.
Case can also influence, like with my PC the GPU was running kind of hot, because the bottom seated PSU's fan was facing upwards competing with airflow from my CPU.

The temperature based overclocking is actually affecting how Linus will be doing GF card benchmarks going forward.
No more open air setups. Will all be in cases now as the cooler used can affect temps, which will affect performance.
PS, it's a hypothesis, not a theory
I had the opposite problem, had to turn the psu round so the fan faced up so it could assist in venting the hot air from the gpu, much better now. Every scenario is different so picking the right case helps a lot.

I think you're hitting the Maxwell thermal limit.
But, GPU boost 2.0 has less to do with temperature or power and more to do with the particular chip you get. You get your standard boost value, which you can see in GPUz, and then an extra hidden boost. Your total boost boost will only be limited by heat if you're hitting 80C, iirc, or power if you're exceeding the power limit. If you keep the card cool and increase the power limit in Afterburner, your card won't increase the extra boost until it hits one of these. Instead, this extra boost seems to have a fixed maximum value and varies per chip. The one on my Galax 970 is 63Mhz. I will only ever boost 63Mhz extra maximum over my listed boost clock, no matter what core clocks I set.
tl;dr: GPU Boost 2.0 will only boost a set amount, even if you don't hit any sort of limit, and this varies per chip. So, even if you and your friend have the exact same model of card running in the same conditions, one could be slightly faster. See some testing here:

CPU should not bottleneck GPU, cpu can make a huge performance difference on how the GPU is utilised.

More cores the better. 6Core i7 or 8Core FX CPU.
Only 6 core I can find is in LGA2011.

Yeah well you didn't ask about platform requirements, or budgets or anything.
You just asked about 4k video.
If you want proper advice you're gonna have to provide more info.

No need to be so snappy all the time with each and every post.
It is funny though.
I wasn't snappy. Guess I'll buy an emoticon pack
