<p>So if you make 0.000000485032112 bitcoin per minute, and let's say 1 bitcoin is $1000.  So your making $0.000485032112 per min, or $0.02910192672 per hour or ~$0.69 per day, but the power costs of running the PC don't make it worthwhile.</p>

How does it make sense to recommend buying mining hardware, when the whole argument against mining was based on profitability? Assuming you have to "invest" a lot more than $1000 in hardware for this to make any real difference, when exactly do you think you will break even? Even if you would earn 0.50ct/day continuously - you'll need over 5 years (!) before you make ANY profit... better recommendation might be to take that $1000 and buy your bitcoins straight out ... it'll give you at least 2 right now - technically - they may be worth a lot more in 5 years ...

<p>Even if you are in solo or pool mining, for the current difficulty (2.4122720023e+11), you will need at least 12Ph/s to gather a full bitcoin block (12.5 bitcoins) in 24 hours.</p>

Interestingly enough, using a pool wouldn't actually make a difference -- it would just allow you to get your rewards spread out over the 98 years instead of all at once. So, let's say you do mine an entire block that's now worth 25 bitcoins, over 98 years. That works out to be .000000485032112 bitcoins per minute, or approximately .00000485032112 bitcoins per block. In short, as @Murch points out, it's probably not worth it to mine using that hardware. Sorry. :/

For solo mining with a single GTX 680, which will produce 120 Mhashes/s, you would expect to find one block approximately every 98 years.

At the current difficulty, solo mining is inadvisable under practically all circumstances. Pooled mining should be done instead.

Furthermore, mining utilizing graphics cards is rapidly losing viability with the release of FPGA and ASIC-based mining hardware, which operates at far greater efficiency. Unless you have exceptionally cheap electricity or have a use for the heat output from the graphics card(s) (e.g. heating your house for winter), graphics card mining is unlikely to be profitable for you.

Additionally, mining with NVIDIA graphics cards has pretty much never been worthwhile, as they are far slower and less efficient than comparable ATI/AMD hardware, conflating the above issues with graphics card mining.
