<p>None. It is unlikely that you will see 1 BTC total mining on that card during its lifetime. See the above link for why.</p>

<p>You may want to try out a calculator first. It is usually easiest to calculate your mining rate by comparing your hashing rate with the current difficulty rate, and then just remove the 1% fee from the pool.</p>

Or, put in another way, you're probably spending in power more that you're earning. Bitcoin is currently dominated by ASICs. I suggest moving to ASIC-resistant altcoins.

kaoD means Scrypt coins - use Coinwarz.com and mine anything with Scrypt.  BTC mining utilizing GPUs has been Dead since July  2013
