Installed and running and boy is it a resource hog.
yup but you can adjust the amount of resources it is using so you can have room to use the pc for other things. only on default settings will it try to use everything.
About the cuda. I know guys on hardocp who have multi card rigs just for folding. it is well known the architecture of the nvidia cores are more dense then even the new intel chips, something like almost 2X the transistor count now.
And when you think about it the video card has more crunching to do with respect to games anyways, where a cpu just executes the code of the OS the GPU has to calculate millions of triangles, dimensional perspective, shading, coloring, angles, effects like fire, smoke and hair. millions of colors, and textures like bumps and water ripples, and its doing it at 50 frames per second.
that is some serious math going on, so using it for something like folding is almost a no brainer.
