The A7V266 C,E,EX & M all use the KT266A chipset.
the C is the standard one.
the E is a C with onboard Raid.
dunno the difference of the EX... doest really say.
and the M is a smaller board using the MicroATX motherboard format.
only 2 pci slots.
none of them are really beter than the A7V333 as it uses a more advanced chipset with extra features.
support for PC2700 ram, overheat protection, blah blah blah.
