It's hard to say until the new motherboards arrive.
I'm currently running a ION Atom based system and quite frankly, it's fantastic. It plays back 1080p stuff without an issue thanks to the GPU offloading. There are just a few other things I'd like to do that require a bit more CPU power.
I'm still tempted to go with socket F1 due to the cost. That and I'm always a bit dubious of brand new tech - I like to wait till they've been in the hands of others for a bit and a few BIOS revisions have been pushed.
