8RDA3I or 8K5A2+ ?

[Cherub]

I am currently using an 8K5A2+ motherboard and I have been very happy with it. I have an opportunity to swap it for an 8RDA3I. I know that the 8RDA3I is much newer, but I also recall that when EPoX has released boards with the same name as an existing product but with an additional letter at the end (particularly "E") they have always been budget boards that overclockers should stay away from. The manual seems to indicate that the usual adjustments are there, but how is the 8RDA3I different from the 8RDA3+ (other than the missing Firewire and SerialATA, of course)?

I find it hard to believe that no one has an opinion!

Heck, I'd be happy just to know what the I in "8RDA3I" means.
