Litecoin mining is the way to go right now (or some other alt coin such as FTC).  Right now a 7950 will mine about 1 ltc a day depending on pool luck and cost anywhere between $0.20-$0.40 a day depending on how much your electricity costs and whether you've undervolted the card to gain better hashes/watt.  Even if you were to mine Bitcoin with the 7950, you'd still end up with around 90% of the value (converted to fiat) compared to Litecoin at today's difficulty according to dustcoin/coinwarz.
