True, but the "value" of a processor is kind of meaningless,
Not really. Compare it to an Intel chip that retails in that price range:

The 8370 will do pretty well against a lot of those, but poorly in some single-threaded situations . . . ignoring the old Core 2 chips, of course.
Then go back to the low-end i5s that it ought to be compared against, and watch it fare less-well. That's why the ~$200 8370 is really more of a $80-$100 chip, and why AMD has thrown in so many freebies to try to move the hardware.
especially since you will have to live with the choice for several years.
Look, I know where you're coming from here, honestly I do, but the guy has already gone so far as to start speccing out an 8370 build that I think he's ready to live with one of those monstrosities for as long as he chooses to keep it. The lower the cost of entry, the less it hurts to mothball the thing a year later for whatever reason.
Personally that's why I think he ought to wait 4-6 months just to get the prices on those boards down a bit. Once FX + decent board goes sub $100 it's just not that big of a deal to buy one and throw it away later if you decide you don't like it. Something tells me that if he's been on a 965 as long as he has that he'll probably like one of these things, at least for awhile. Until Zen-itis gets him.
So the question becomes " is the initial cost savings worth living with a more power hungry and generally poorer performing processor on an outdated platform for several years"?
Who says he has to live with it for years? He can just punt on it and buy something better later, if that's what he really needs to do. Resale will be low but thems the breaks kids.
I probably fit that definition, but even I won't touch an FX chip. That should tell you something right there.
What it tells me is that it has more more infrastructural support costs (board, PSU) than you generally like. Though I must admit, I can't bring myself to touch one either. Every time I think about grabbing a used Sabertooth and an 8320e, I remind myself of how badly some of my code runs on Vishera compared to Kaveri, and it pulls me back.
The only useful attribute of those CPUs is that they can heat your home (if you live way up North), that's about it.
Shhh don't get Abwx started . . . wait, too late. Carry on then.
