I found one thing on that chart sort of strange. They list the budget minded 8K3AE as having AGP voltage adjust, while their "higher end" boards like the 8K3A, 8K3A+, 8K5A2, 8K5A2+, and the 8K5A3+ do not
Strange that,since if you go to Epox site it does say, "AGP voltage settings are adjustable by BIOS " for the
Epox 8K5A2,says the same thing for the 8K5A2+ as well.
E version I believe is the Economy version,normally has less features.
I did say Epox had too many boards out at the moment
