The fact it's on SSD is irrelevant to the CPU question. The SSD will just make some areas load faster, travel outside may be a tiny fraction smoother (probably no noticeable difference).
The slightly weaker CPU probably won't have any noticeable effect on normal gaming, although it might give slightly lower framerates with areas that have complex lighting (more light sources, more cast shadows) or really convoluted layout (more CPU load calculating what bits of the vault or building you can see through the doorway through which you can see a window into a long hallway). Possibly certain graphics settings might pull your framerate down more than on a stronger CPU, but until the game's out we can't know.
Where you'll most notice a CPU slightly below recommended is if you try to use a lot of script-heavy mods.
