I think it might depend on what you are using them for and/or your business. If you sell face-to-face, good cards might be important for your marketing efforts. It seems it would matter less if it's contact info for people who are trying to sell to you. If you are printing a few to get the attention of VC? They will probably say, "This is how the company's going to spend my money if I give it to them. Is it sensible?"
I do a lot of face to face selling, and get a lot of cards. Your card is going to get lost in the noise; there are people out there with metal cards, die cut cards, probably glow in the dark neon cards. I wouldn't lose a minute's sleep over yours, as long as it's printed on heavy stock.
Here's mine; the back of the card has actually gotten us business. =)
