I suggest you buy dividend paying shares in a mining company like ASICMINER. You get weekly payouts, and the share prices are rising presently 
You can grab some pass-through shares on bitfunder.com or btct.co.
Also a new asset, PAMB on bitfunder has paid weekly dividends at ~2.5% of share price. This is a spectacular return on investment, but it smells to good to be true.
Alternatively, grab a ATI 7870 and mine some litecoin. You'll be getting a solid video card and get a decent hashing rate.
If you want to mine BTC personally, you need to grab some ASIC hardware. There have been a lot of bulk chip sales lately, so I suggest you wait a couple of months, because I think the hardware economy will be more competitive, and it will be more of a buyer's market. The difficulty will be higher then, but with all the new hardware coming online at the moment, you want to avoid paying super-high prices for ASIC tech at the moment.
