Truecrypt doesn't use the TPM.
Neither of them (like basically all desktop boards) have a TPM onboard; they have a socket where you can insert one.
TPM isn't particularly useful for encryption, though. It's also a massive pain as it means that if the TPM dies, you can't decrypt the drive without a special recovery key.
I wouldn't normally recommend TUF/ROG boards. They tend to be pricey and you're not going to use all the extra features. You're paying for the brand + bling.
