Default "Professional High Speed" SDHC?

I bought a Nikon D5000 a couple months ago and with it I got a 4GB Promaster "Professional High Speed" SDHC card. I wanted to get a couple more, and found that I could get two 4GB SanDisk SDHC cards at Costco for about $25. My question is if there is a difference. The Promaster says, "Professional High Speed" and the SanDisk ones do not. I am really new at this.
Will the SanDisk cards perform any differently because they are not "Professional" or "High Speed"? Is it all just different wording for the same thing?

SanDisk makes SDHC cards with different speeds, as does ProMaster. What matters is the Class of the card. (See http://en.wikipedia.org/wiki/SD_card#Speed_Class_Rating )
