Been looking at cards for this machine.

Noticed that there are quite a few which give a figure for CUDA cores.

Does a higher number of CUDA cores give more results when doing CUDA work units?

Comparing the details of these two for example:


KFA2 GeForce GTX 580 Anarchy 1536MB GDDR5
772MHz Core, 1544MHz Shader, 512 Cuda Cores, 2 x DVI, Mini HDMI


Gigabyte GeForce GTX 560Ti OC 1024MB GDDR5
900MHz Core, 1800MHz Shader, 384 Cuda Cores, 2 x DVI, Mini HDMI

Which would be better and why?

The 580 is faster than the 560 of course, but according to Wikipedia, the 560 Ti has a better Gflops per Watt number.

If CUDA is what you want, I believe the GTX570 gives the most bang per buck per watt....
