Building a Desktop Computer for Math/Physics

[Dr Transport]

Let me repeat waht I said:

It is true that you can get great calculational performance on GPUs, However, you need to be using code that is specifically written for GPUs. If you aren't writing the code yourself, or using a program specifically written for running on GPUs, it's not likely you will get better performance. You're better off saving your money or spending it elsewhere.

I looked at using GPU's when I was in industry a few years ago, they were fast but not nearly as accurate numerically as we had wished, that is why we went towards pc clusters...

They mostly use 32 bytes floats, but some of the newer ones can work in double precision (64-bits).
