With the release of new bitcoin mining hardware, GPU mining (at least for me) isn't worthwhile anymore.
Maybe 8 months ago, I had a few cards mining.
4770, 5770, 5830, 5830, 5850, 5870, 6770, 6850
At the difficulty level at the time, I think I was around 1300mhash/s. Now 1 ASIC miner will use less electricity and put out way more hashing power than that.
“The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles.” - Jeff Cooper, Art of the Rifle
