He also has all his source code available for download in the description.
I am almost certain that your performance would increase significantly if you choose GPU over CPU. That has been my own experience with background subtraction. I saw a vast increase in performance on a quad core intel vs. a lower-to-middle end Nvidia GPU.
In regards to GPU acceleration: Go for the latest generation Nvidia card you can find. The amount of CUDA cores is what is important. I see that both the GTX 295 and the GTX 570 has 480 CUDA cores - if those two cards are readily available to you then I would go for the GTX 570.
If you plan on buying a graphics card then check out the latest generation. With the 600 series they increased the amount of CUDA cores quite significantly. Check out this list and look for the first number of the three in the "Config core" to get the amount of CUDA cores: http://en.wikipedia.org/wiki/GeForce_600_Series#Products

I think the 570 is not only faster, it will also mean that you don't have to worry about getting the code to work on a dual-GPU setup.
