The article mentioned above noted that Capitol one is not charging anything for forex transactions, even the 1% Visa/MC bank fee. I can confirm this with a trip I did last month (and the exchange rate used was also pretty competitive). Right now, Capitol One is the best card for overseas travel for me (since I get 1% cashback on all purchases).
