ah CUDA basically is a virtual system

its a load balancing tool as well as a data converter.

CUDA is used for stuff like video encoding, tesselation, folding@home, seti@home, server processing (blade servers), and its also good for 3d video editing

in gaming beyond tesselation it does little.. and tesselation only really applies to benchmarks and dx11 compliant games such as stalker cop, metro 2033, dirt2, bfbc2, WoW*, dowII, total war: shogun 2, facry2, ptboats: pacific gambit, N:TW.

So do I want it on or off??? Boost performance or not? from what I understand it wont help?

Theres no advantage to turning it off. But you also arent doing anything that actually takes advantage of CUDA. So, it doesn't matter.
