28000 khash/s- Is it worth it?

[flawlessminds]

Just starting off mining on my 27inch late 2009 imac. My Graphics are ATI Radeon HD 4670 with 256MB RAM. Using DiaboloMiner. Not really sure what a "good" rate is for a home computer, so my question is: Is it worth mining at a rate of 28000 khash/second?

Thanks for your assistance

You're projected to mine $6.56 worth of BTC per month.  I'd put that on the side of "not worth it".

More like $6 worth, as difficulty is projected to go up twice per month.
