Are you putting-in active bass-traps? Geeez man. A foot?
The basic wall and ceiling design, subject to fine tuning by the architect, is as follows:
Outer sheathing - 2 layers of 3/4" plywood with Green Glue (acoustic adhesive) and screwed to studs.
Outer stud wall - 2x6 studs filled with insulation, no interior side sheathing.
Approx. 2" space, then,
Inner stud wall - 2x6 studs filled with insulation, no exterior side sheathing.
Inner finish - Up to 4 layers of drywall all screwed and glued with Green Glue.
This is what's called a room within a room design.
Interior finish, such as the above questioned bass traps, will depend on actual acoustical testing of the room. We should be able to keep recording even with a railroad main 1/4 mile away.
That's the basics. The details to accomplish it are much more complex. This is to be my "life after the railroad" so to speak.
Nice SSD subject matter hehe. I could talk about acoustic design all day and not get bored.

Edit: Gotta get some science in here somewhere. Did you know that the surface of a star, our sun for example, is unbelievably loud? Not only extreme temperatures, but extremely noisy.

I saw a thing on tv once that said you need to seal the space between the two walls or sound will still migrate thru, They said YES that means drywall AND taping all the joints, no paint or sanding required though on the soon to be covered up first wall.

Yes I knew that, I like to watch alot of Science shows on tv where I learn alot of weird stuff. Other people don't always like it so much when I share though!! Like did you know MOST people eat 6 to 8 spiders per year, WHILE they are SLEEPING?!!!

I could have gone my entire life without that piece of information. I have enough trouble sleeping without thinking about that.
Just think of it as midnite snacking, they are just harmless things full of protein and almost no calories. Do you ever wake up thinking I am 'full' and don't need to eat too much breakfast today, maybe that's why?
My buddys wife takes Ambien every day to help her sleep, he woke up one morning to find the bathroom was SPOTLESS and the mop and bucket still out, they were NOT out the night before. Turns out she got up in the middle of the night and cleaned the bathroom. I told him he needs to put little guide ropes to other parts of the house that need similar tlc and then one leading to the mower. She can do the mowing while he is still sleeping, and she will wake up in the morning with no memory of how it got down, and he can take the credit for it!! I told her to tell her doctor about her episodes and she nearly bit my head off, I think she is addicted to it!!

A lot of good advice has already been given in this thread. And some good humor ;)
However, I did not yet see an answer to the original question: do PCIe-SSDs consume more bandwidth than others and do they thus disturb the crunching GPU?
There are a few cases to consider:
1. GPU: PCIe lanes built into an Intel CPU, SSD: connected to PCIe lanes from the chipset
In this case the answer is an obvious "no". The GPU has its dedicated pipeline into the CPU, whereas the SSD traffic is passed through the chipset and DMI interface to the CPU.
2. GPU and SSD: PCIe lanes built into an Intel CPU
In this case the SSD might force the GPU into 8x mode instead of 16x, just by being there and sharing the connections. Depending on the project this can affect GPU performance.
3. GPU and SSD: PCIe lanes from the chipset
In this case both devices have to share bandwidth, and the GPU could be in dire need of more bandwidth. However, the situation is not as bad as it may seem initially. Making an SSD faster does not magically increase the amount of data to transmit. When ever you've got something to read or write it just happens faster than it used to. The GPU may be disturbed a bit more, but for a shorter time - on average this should not matter.
And if an SSD is connected via SATA the data has to move through the chipset and the DMI link to the CPU anyway, so it actually doesn't matter if PCIe or SATA got them into the chipset.
Regarding the question "SSDs for dedicated crunchers": as others have said that's surely a waste of money. They save 4 - 7 W over an HDD, which saves you about 8 - 14€ per year at relatively high german electricity prices. SSDs don't get as hot, sure, but power consumed equals heat dissipated anyway. Since you pay for power and not heat that's all we need to care about (10 W of heat dissipation is thermally negligible for a PC).
I can see two nice alternatives: booting from the network. If you've got a small farm this could be worth the hassle of setting it up, since you save per cruncher. Or using USB sticks. 16 GB with decent perforance cost almost nothing compared to even the cheapest SSDs and will last for quite some time. If the flash is worn out after a few years it should have been worth the investment.
