I know you probably don't want to hear this, but trying to solo mine with your gpu is like trying to dig a gold mine using only a spoon. It's theoretically possible, but it's not going to get you anywhere. If you have your heart set on mining, I would try MiningRigRentals or NiceHash. If you time it right, you can get some pretty low rates for scrypt mining on NiceHash.

Good luck and happy mining.
