Well, it all depends on how the US actually splits. Best case for the CSA, they keep the "New Mexico" Territory, Indian Territory, South California, and the Border States, basically all slave owning areas and everything below the Mason-Dixie Line.
They'd be able to stand as a proper competitor to the US and Mexico in terms of power and resources in that situation.
Worst case is they only have the actually seceded states, as that would have been a loss of resources overall.
