CUDA clock and core questions

[zcoot]

I am just wondering if CUDA on Nivida cards affects playing games at all and if not what applications can it help in?

My quick assumption would be things which are optimised to run on multiple cores will benefit from it but that is just a guess.

Also I read that it uses system memory; could that affect bandwidth and cause performance drops?

I am mainly making this the deciding choice between a 7870 and a 660.

Any help will be nice.

Cuda has more to do with things like Photoshop. I'm sure others will no more about which applications support it.

For gaming purposes I would side with the 7870.
