THere is a lot of CPUs in the list for this mobo, which one is the best to buy?

Here is the supported CPU list:

Also this motherboard is sitting for a year, will the latest CPU start to let me update BIOS in order to be compatible with it?

Thanks

A8-3870K is the highest APU
Athlon II 651K is the highest CPU.

They list needing bios updates for these two but I think it will boot up with an older bios, possibly with "AMD model unknown", just need to update for full detection.
