Certainly if IPMP is used, then individual TCP connections will hash.

In the past, I've used many systems with multiple nics on the same
subnet without IPMP and usually one of them has almost no outbound
traffic.  All the traffic was using the other interface.

This behavior may have changed with some release or patch, but I don't
have a box I can use to test it right now.
