Well can we try to add a theme...
This drop puts AMDs chips and a very good price performance for a Quad core system, 200 USD for a quad core is almost unthinkable even if it is not as fast as intels counterpart. Most consumers wont ever notice anyway. With the Spider system this will make for a very affordable gaming rig.
I am sure at this point AMD is not making much if any money off of these chips but it may be enough to kick some people into hitting the "buy" button. Once people see these CPUs are not the worst mankind has ever seen then AMD may be able to gain some more foothold for the time being.
