My plan was to buy an ivy bridge processor and start learning opencl. The new imbedded HD graphics support opencl 1.1. There aren't particularly fast(esp for DP) but it will be enough to program with and debug. You could then take the code you have developed and run it on Amazon's cloud service. You could rent some time with a gpgpu, enough to do some quick benchmarking for very cheap. This was my plan. Was gonna upgrade my system and wanted to start learning opencl but didn't want to drop spend too much if it proved to be too much trouble.

That being said looking at the 210 it has compute capability 1.2 which means it does not support double precision. You can still do single precision work with this card but it would probably be better to just grab something a little newer.

DP wasn't supported until 1.3
