-In principle, all the Nvidia CUDA enabled cards should work, however a really cheap card can result in only very small calculation speedup. The best choice are gaming cards, that are already very powerful, but still not expensive like special computing ones. GSvit is intentionally written to work with floats wherever on graphics card possible to get reasonable speedup on older and less developed cards (as the doubles were supported later and also are still a bit slower).+In principle, all the NVIDIA CUDA enabled cards should work, however a really cheap card can result in only very small calculation speedup.
