In my research lab we have computers that are indeed specially designed for specific tasks.
But these computers were made many years ago. With current technology everything these computers do, can be done on any computer anywhere. The reason they created these computers is because our hardware wasn't advanced enough to handle the tasks they wanted to handle to do the scientific research they wanted to do. So they specially designed hardware to work on specific tasks to improve technology.
But since then. Our technology is so much more advanced, there simply is no need. All you have to do in scientific research nowadays is buy the latest computers commercially available, create a cluster, then run some software and you can do just about anything.
So if your developing software, you can do anything on any modern day pc no matter how good it is. If you want your code to execute fast, you should want a recent up to date processor. It's just nice to see things happen in 5 minutes instead of 30 minutes.
