I'm having stability issues with pop warband modification. The issues, I've encountered so far are fps drops during battles and blank screen crashes. The latter usually occurs once I switch menu's.

Post back if it did or didn't help. (+ you can combine it with turning on Load Textures on Demand, which is in pre-launch->Configure->Video).
(PS: having a GeForce560Ti will not help from crashing because it is your RAM that is the cause)
