would I be better off using my CPU

No, your CPU is likely much slower. I reckon you'd probably only get around 8 KH/s with your CPU.

I Googled oclHashcat which led me to this site. I downloaded oclHashcat for NVidia 1.31, but cudaHashcat is what actually downloaded.

oclHashat is for AMD cards, cudaHashcat is for Nvidia cards.
