So I'm semi confused here. I'm using bitminer and I'm using both integrated and dedicated GPUs (I have an AMD integrated so it's good) and I'm getting about 110 MHPS, is this good, where does my wallet come in, and how do I get cash from this?
Assuming you're using BitMinter, your BTC is left in the BitMinter servers. Waiting to be retrieved by you.
Bitminter.com -> Login -> My Account -> Account Details
It'll show you how much BTC you've mined (excluding the %4 for the server). It might show nothing if you're now starting. It'll take a couple hours to update the value.
Also, if you're getting 110 Mhps total; You're making 0.01 BTC a day (Which around 0.58 USD a day). Which, to be honest is pretty slow.
then you can sell those btc on mt gox.
I wouldn't suggest Mt. Gox.
Registration requires so much personal info it's a bit suspicious.
