This sounds accurate to me.
Tom's also doesnt go very in depth, at least that I've seen. Benchmarking only a handful of games in a single resolution does not to me constitute a substantial investigation. Don Woligroski is an intelligent man I'm sure, and hes entitled to his opinion, but thats what it is, an opinion. Ironically, thats my opinion of his opinions
On the topic of picking between the two, I would suggest looking at an 8120 if you want to go the bulldozer route. The 8150 is essentially identical to the 8120, its just clocked higher. Since both of them have unlocked multipliers, its unnecessary to pay more for the 8150. And the 8120 currently is not much more in cost than a 4170. From newegg, the prices are 140 and 170 respectively.
