I have an Antec Performance II SX835II case that supports an ATX motherboard. Will it also fit a uATX board?

Will a Micro ATX board fit in an Antec Performance II SX835II?

It probably doesn't because Antec doesn't specify that it's compatible with mATX mobos. However most ATX cases will also accept mATX, but I won't count on it for this one.
