To expand on what ethereal wrote which is spot on, for me the question was do you want to have that lower performance in some games or is it worth the ~$20 to get the 3570K? Or whatever ~$200+ chip Intel has out now. I went with the 3570K because I didn't want to have slow downs in any game. I wanted the fastest/best, and it was worth it to me to spend the extra $20 to get the 3570K. As bigtroll mentioned however asking about one part might not be the best. Hard to suggest parts when you can't see the whole picture.
Edit: Here are a few games where the 8350 has trouble keeping up.
