60D SD Memory Card Speed Recommendation

I'm about to order a new Canon 60D and have not previously owned a digital SLR. Although I'm not that much into high speed sports photography, I would like to order a decent speed SD memory card for the 60D. I would probably be shooting in either RAW or RAW+JPEG formats. Most of what I'll be shooting will be candid family shots and nature (landscape/wildlife). Any suggestions regarding the speed of card needed for such applications starting out as a new digital SLR owner?

Thanks in advance!
