What would the best option be for a Crunching Machine.

Something at the low end. I was looking at the Raspberry PI3 and then I know you have the option of GPU Crunching then the likes of CPU.

Theirs so many options available I dont really know were to start. Do I go down the route of GPU, Raspberry PI or is their something that can give something on specialised platform for SETI like they do with BitCoin Mining.

If anyone’s able to advise I'd really appreciate it.

What would the performance be with a PI 3 .

A discrete GPU crunches the most, somthing like a GTX1050 costs ~ $120 to $150.

pi3 = days per task.
basic PC CPU = hours per task
GPU in PC= minutes per task

A succinct summation. +1

What would be a Good GPU too crunch on. Something at the low end of the scale. Would something like a 6xxx AMD or a minimum of a 7xx or even 9xx for nVidia be the only option.

Thanks for your responses.

For reference, here's my RPi2. A RPi3 should do better.

First remember that a GPU is useless without a PC host whereas a pi is a complete if rather slow computer.
Assuming you have a PC to host the GPU then I would look at the nvidia family not the AMD family as the nvidia offerings appear to perform better and require less effort to get crunching than the AMD offerings at the same price point.
So which group of the nvidia range to look at? Nothing older than 7xx is worth considering as they are now well below the power/performance curve. Of the 7xx only the 750(to) are worth looking at, but they are now at, if not beyond, their production life. Which leaves us with the 9xx and 10xx sets. The 1050 and 1060 are getting good reports for price/performance.
But it really comes down to how much you want to spend in terms of both capital and running (energy).

Been looking at the Palit GeForce 1030 with a drain of 30W and powered by the PCIe Slot.

What do you make of this card and I'm guessing its got to be better than having nothing.

I'd spend $30 more and get https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=gtx1050+video+card&N=-1&isNodeId=1
Edit: The GT 1030 has 384 Cuda cores, the GTX 1050 has twice as many, 768

Just logged in and seen I have my 25% Top Contributors badge back. This makes me want to invest in my set up even more. (y) ..

A GTX1030 will be better than just a CPU, but not significantly. Others have already suggested a GTX1050. A lot of folks have found that the big step in performance between the x30 and the x50 GPUs to be well worth the extra spend. On paper the performance of the 1050 should be more than double, if not treble that of a 1030 for about 20% extra.
