Nouveau on GTX 650 ti causing instability and lockups

I put a GTX 650 ti in my privacy PC because the nouveau driver for it doesn't require non-free blobs. A few days later I started having instability issues like session crashes and system lockups. When there's a session crash and I log back in, Problem Reporter notifies me that xorg-x11-server-Xwayland has crashed. So is this probably just a buggy nouveau driver, or is there something I can do about it? Maybe a compatibility issue with another component of the system? Are there any other video cards that don't require non-free blobs? It would kinda suck to have to go back to the old Radeon.

CPU: AMD FX-4300
Motherboard: MSI 760GMA-P34 (FX)
RAM: 8gb+8gb, but I've tried every stick of DDR3 at my disposal

PSU: a 500W that I know for a fact can power better cards
