I wouldn't call the 5700U a winner. It was/is priced the same as the FX5900XT for so long yet the FX5900XT outperforms it. A very silly idea in my opinion. The FX5700NU on the otherhand was a sweet deal at $130 because many overclock well. 5700NU is good for the money, 5700U is not.
And you forgot to mention the FX5200U. Less than $100 and it perform decent in most games as I mentioned earlier. Obviously not an ideal card, but acceptable provided you don't play above 1024x768 or use AA/AF.
