Graphics Card Uses

Hey guys I am going to a university in a few weeks so I got my uncle to send his old gaming computer and I am going to turn it into a server for the dorm. I plan to use it for VOIP, FTP, web site, etc. He sent a graphics card and I am wondering if I could use that graphics card to process info or something?

don't some cryptocurrencies use graphics cards to mine for them?

I heard about that, this isnt the most powerful card though so I am looking to use its power to do something.

GPUs are very good at performing nested for loops. If you can think of an application that uses lots of nested for loops (examples: matrix transformations (robotics/games) & image/video processing), then you might be able to use GPGPU libraries (CUDA/OpenCL) to get extra performance.

But not too many user applications require GPU computing. GPUs are great at repetition (they require it to make up for high latency of random data transfer).

You could consider help SETI odr CERN with BOINC (just google it). It runs on my server when there is not much load (so basicly the whole time). With a GPU it perfomes the shit out of the Problems you have to solve (well, not you. Your PC)
