If you are open to a used video card I have a Radeon EAH6850 that is left over from my last upgrade. It works perfectly and even though it's 3 years old it is a way better card than the GT 630. I'll give it to you for $60. http://gpuboss.com/gpus/Radeon-HD-68...e-GT-630#specs
Edit: You might need to check if your power supply will be good enough.
