"FALSE", this has "NOTHING" to do with framerates... It's about "CAPACITOR" whine, and Capacitors start to whine when they are stressed, about to go out, or have "TOO MUCH" current running through them due to an underpowered/inefficient PSU.

the OP clearly states he only has this during the black screen, when the gpu is running at 1000+ fps, audible whine at these framerates is very common. I've noticed it with half the cards I've owned. I doubt the gpu is fully stressed during the black screen, you need a complex scene for something like that, so it's not too high load.

That is a "Component" issue with the Video Card, not frame rates... The "Capacitor" whine is due to stress, and what do you think the stress is..??
.
EDIT: People complained on all multitudes of Sapphire's offerings that they are getting coil whine in the past, what is the exact manufacturer & model of the Video Card, perhaps looking up know issues would shed more light on this issue.. Coil whine is physical noise generated from the movement of the coils in chokes.
.
The 2 quickest ways to test coil whine for your GPU:

1) Run Windows Experience Index and see if your GPU squeals;
2) Run MSI Kombustor GPU Burn in Test called "Triangle of Death" (full screen).
.
Also E.M.I. has been known to make nosie confused with "Capacitor" whine, a ground loop isolator will remove that noise if it is E.M.I., and not a "capacitor whine issue".

PSU Cap whine..

the worst whine I've gotten from gpu's was in the menu of stalker and stalker call of pripyat.

If I start that game the menu runs at 2000 fps, if I then put my ear right next to the computer I can hear very faint squeaking noises coming from the system. My previous 2 gtx 260's had very audible whine in that menu. If I run unique heaven I get 100% load on the gpu, but dont hear the whine.

Again, it's not the "Frame rate's" fault, it's the hardware... Frame rates in and of them self are not the issue, it's a hardware issue.

EDIT: F.Y.I. A PSU does "NOT" deliver anymore power than what the system uses/needs.. A system running a 1000 watt PSU, but only has a 600 total watt consumption will only pull the 600 watts it needs, and the PSU will only deliver those 600 watts, it will "NOT" overvolt your system, it is based on demand from the PSU, and "NOT" the PSUs maximum output spec..

Please look at the PSU supply Curves of most of the PSU's
Most of the PSU have their Power sweetspot at 45-55%
With a big Fallout below 20% the 80+ Mark is even not given and they don't need to hit the 80+ Effiency.

So having a Comsumption of around 250-300 Watt. The sweetspot would be Dead on with an 500 Watt PSU.
A PSU with 650 Watt has a load of 30%-50% depending on the Game. And a bigger will be more Inefficient.
An Uprating as you suggested would putt the PC in the 20% or less Zone.

He got a
3770K Max TDP= 77 Watt
AMD 6970 Max TDP=208 Watt
For the Mobo around 30 Watt
Per HDD= 8 Watt.

Max Consumption of the System= 323 Watt
Average should be 250-270 at load

So a 500-550 Watt would be best as the GPU Manufacturer recommendated.
You the Best PSU for a PC is when it runs with 60% load at Max TDP.
Then it is the Best for the PC.

#1. Perhaps you didn't see where i said "A little Bigger" than needed...
.
#2. I didn't advocate 1000 watt PSU for a 600 Watt draw..
.
#3. I also said, and I "AM" correct... "F.Y.I. A PSU does "NOT" deliver anymore power than what the system uses/needs.. A system running a 1000 watt PSU, but only has a 600 total watt consumption will only pull the 600 watts it needs, and the PSU will only deliver those 600 watts, it will "NOT" overvolt your system, it is based on demand from the PSU, and "NOT" the PSUs maximum output spec..
.
PSUs do "NOT" run at their MAX capacity unless they are called upon (by the system) to do so..
.
Buying a PSU on the edge of it's max specs to power a system is a "NEWB" mistake.
Also, I didn't say that was the OP's problem.
.
Also, I did "NOT" say anything about being inefficient due to have a "HUGE" power supply, I simply stated the truth by saying the PSU will "NOT" deliver more power than is requested by the system. A slight inefficiency due to having a bigger power supply is "NOT" an issue, unless you are counting your power bill, BUT "underpowering" any device is the worst, called a brown out, I have seen it kill a friends Video Card..
Having a little bigger PSU than needed is an advantage, where as having a PSU running on the edge of it's max output, is a time bomb waiting to trip it's overcurrent protection..
.
If you read correctly I said at the bottom of my post "I wasn't saying he needs a 1000 watt PSU either."
.
I was using the 1000 watt versus 600 watt draw merely as an example... NEXT?

And there is the error, a lot of PSU have problems with Voltage Stability when they go below 10% load,
which they do when the PC idles. And this wears the Voltage Regulators of the Board down.

There had been a lot of Scary test with PSU at idle power with 3,3 and 5 volts at the 10% limit of the Specs.. so yes they are okey but unhealthy for the boards in this Area. When a PSU gives 5,5 Volts and 3,7 Volts at 10% Load then it is not good for the Board... and there a lot of PSU's out there.. which only stabilise at 10%..
Even Enermax go out with 1.5% at the low load Area. Yes 5% are allowed for most up to 10% for some but it is not good for the Board.


And a modern Pc uses in Idle about 60 Watts...

Yeah, but limiting the framerate to something sane fixes it, and most manufacturers dont replace whining cards, although you can always try.

Not buying a cheap PSU with poor voltage regulation will solve that problem.. I.E. don't cheap out with an Athena PSU.
If you are running a ASRock mobo, then you might have a problem with smoking a VRM, but again that's an issue with the quality.
.
Intel Mobos usually have very decent power Phase Designs, and I have never seen a "little bit bigger" PSU smoke a VRM.
.
I have "NEVER" smoked the VRM... But I have watched an MSI board go poof trying to unlock, and overclock a Phenom II 960t from a 4 to a 6 core and OC it... It was a Micro ATX board with a crappy 4+1 phase...

Thank you everyone for the insite and advice. I am going to try the V-Sync and see if that resolves the issue. I am also going to run the Kombustor to see if I can force the whine. I'm not convinced that I'm looking at an imminent hardware failure but we will see.

Finally, someone attributed some blog post to me. The link is no longer there so I am obviously missing the joke. Regardless I do not have a blog and no knowledge of what the poster was referencing. I hope it was not a derogatory jab at me.
