How much can I profit from mining using single HD6870 using deepbit.net?
Is solo minining worth trying using this setup?
Looking at the deepbit stats you can see that with the current pool rate: 3115 Gh/s they get about 60 blocks a day at the current rate. If you compare your card to others ( https://en.bitcoin.it/wiki/Mining_hardware_comparison
) you would get about 300Mhash, solo mining (at current difficulty) would statistically speaking take you over 100 days for one block of 50 BTC + transaction fee.
