It stomps a Q8200 and costs less.
Drinking tonight? Without a doubt the Athlon X4's are an incredible value, but it doesn't stomp the Q8200. Even a Phenom @ 2.6-7ghz loses out to a Q6600, which the Q8200 is mildly faster in comparison. Is the Athlon X4 faster than a Phenom 1 X4 clock for clock? Absolutely not.
In many previous threads I've compared stock and overclocked benchmarks to Phenom 2 X4 systems. At stock, a Phenom 2 X4 is mildly faster than the Q8200 is most tasks. Only in Cinebench does the Phenom seriously get a win. Overclock benches shows the same story. At 3ghz, the Q8200 is comparable to a 3.5-3.6ghz Phenom 2.
If I was building a PC right now, I'd most certainly but an Athlon X3 and a board to unlock. Just for the cheap price and AM3 support. The Q8200 still holds its value for routinely hitting $99 and $119 price points. I bought mine a year ago in a combo deal (Fry's, ECS G31T mATX motherboard) for $189. It overclocks ridiculously easy and has held it's value very well.
Simple fact: Athlon X4's are a great value, not great performers.
