Motherboard: H77MA-G43
Video card: GeForce GTX 650 Ti (I think it's 2GB, with 2GB shared video memory)
Ram: 8 GB (can't remember the speeds)
Processor: i5-3350P @3.1 GHz (I think it's 4 core)
Sorry for any vagueness. Just wondering if I really need to bother upgrading before getting Fallout 4, and if so, what should I upgrade without having to replace my motherboard?
