I've had some decent results with P4 and Socket 939 motherboards but after that, not so much. I don't know if that's a bright-line rule, but it seems to hold with my gear.
My quite current Socket AM3+ board with six-core CPU and 16GB of RAM (to be precise, an ASrock 890FX Deluxe5) has a floppy connector (one of the reason I chose that board), and it supports FM and MFM.
