I shoot in RAW only and extract all the JPEGS from the flash card later using a small piece of software called Preview Extractor, this way you don't take up unecessary card space with extra files that you already have embedded in your RAW file, also you don't need to run a fully fledged program like Photoshop or others just to see your JPEGS .
Follow this web link thread for more info.

I use Nikon CaptureNX 2.2.4 for all my RAW files, it's far more than just a rendering tool and it's used by many on this forum, I would fully reccommend it.
