A tiny fraction of a millisecond. Completely negligible.

well, depends on the velocity factor of the cable you're using. use that number to divide by the speed of light in a vacuum, and calculate how long it takes for the calibrated velocity of light through the cable to travel 2 feet.
 
Just so you understand, this will be a purely academic discussion as the facts will plainly be evident. it will be to the -n'th power in fractional seconds.

It will add latency that is only measurable with equipment that is at least 3000 times the price of that cable.

Oh lol. I thought he meant a fifth of 1. Sorry!

The issue is when you are have 1 card those "toggleable physx settings" are going to put a massive strain on the 1 card since the card is pumping out the gfx and doing the phyx processing.
In games without a togglable setting (project cars) the cpu handles phyx no matter if you are on nvidia or AMD gpus
If you have 2 cards leaving it on auto is best but you would be better of setting it to gpu generally speaking.

The option to set it to the cpu is mainly for amd users i believe. But in most cases, as long as your cpu is not already bottlenecking the gpu, there shouldn't be much of a difference. 
 
I take borderlands 2 as an example. I used to hover around 60 fps at 1440p ulta on my gtx 770. After switching to my r9 290 and setting the cpu to handle physx, I am getting close to 90 fps at 1440p ultra. And quality-wise I can't tell the difference.

Physx is highly parallelized code which takes advantage of the thousands of cores inside a GPU

in theory gpu but the games that use physx optimize it so horribly i haven't noticed a big difference between cpu or gpu lol

Hell no Ninja that shit works best on the GPU.

GPUs are much more powerful than CPUs.
 
PhysX is designed/intended to be run on the GPU.

I'm curious to know if PhysX runs better on my GPU or CPU. A lot of people say if your CPU is more powerful than your GPU, then you should set it to the CPU. Meanwhile, other people say PhysX is designed for a GPU architecture, and if you set it to the CPU it will put a lot of unneeded strain on it. Does it even matter what you set it to?
 
Thanks in advance!

Holy shit it worked! Back to 100 degrees! Thanks everyone for the help!

I don't really see why it matters, he needs help with his PC, he came here to get it.

Thanks for everyone's help! Front fans are intaking and back are exhausting now. GPU is WAY cooler.
