Unfortunately, you don't tell maker and model of your motherboard, only of the CPU that's mounted on it.
So nobody can tell, since CPU's don't have slots (only motherboards have).
Another limiting factor might be the PSU. Some cards need more power than offered by your current PSU. But you didn't tell about that either.
