FYI, I got the following email from AMD Australia this morning :-
I just hope that we start seeing some more Lower-Mid Range Motherboards from the Manufacturers soon.
We have received notification that the AMD Athlon™ 64 3400 & 3700 processors in the 754 pin package will come to their end of life this quarter. To that end we expect to see these parts disappear from the channel during the July-September timeframe. These processors will still be available in the 939 pin package.
I just hope that we start seeing some more Lower-Mid Range Motherboards from the Manufacturers soon.
