Stay away from nVidia GPUs with a low second digit (x20, x40). | Stay away from nVidia GPUs with a low second digit (x20, x40). Higher 2nd digit means more CUDA cores. | ||
The number of CUDA cores matters much more than a few Mhz in frequency, since you can process more, in parallel. | The number of CUDA cores matters much more than a few Mhz in frequency, since you can process more, in parallel. | ||
Also watch out for bus width, as that has a big impact on data throughput. | Also watch out for bus width, as that has a big impact on data throughput. The more CUDA cores it has, the better. A GTX680 is lots and lots and lots more important than a CPU with a zillion cores. | ||
In case of doubt, go for an older generation x60 (460, or 560), even a 260 would be much more of an improvement than the 620. Basically, Nvidia cards compile GLSL shaders and OpenCL kernels into CUDA kernels (sort of), so more CUDA kernels = more shader power | In case of doubt, go for an older generation x60 (460, or 560), even a 260 would be much more of an improvement than the 620.

Thorsten mentioned in another thread that he purchased a computer with an NVIDIA GTX670 that ended up not being fully supported under Linux, so I'd suggest to be really careful here. | Thorsten mentioned in another thread that he purchased a computer with an NVIDIA GTX670 that ended up not being fully supported under Linux, so I'd suggest to be really careful here. | ||
