[Newbie] Can CUDA Toolkit 7 be used with Fermi GPU card?

I am new to GPU and CUDA programming, and I am just starting out, so please pardon me if my question is really silly.

We have a few-years-old computer with a Fermi GPU card. Can this be used with the CUDA Toolkit 7? Or do we need to purchase a Kelper GPU card?

Thanks for any help.

It will work.
