Is mining still profitable?

Now as ASICs flood into the hands of miners, GUI mining will probably shift to Litecoins where the returns are about the same.  You can trade LTC for BTC on btc-e.com.

Yep, from https://en.bitcoin.it/wiki/Litecoin, apparently GPUs are at least as good as other specilized hardware.

Everyone talks about how huge your electricity bill would be, but I have a real time monitor for my electricity usage, and it costs about £0.08 per hour to run my PC (with 2 monitors) at idle, and about £0.085 p/h to run it with GPU mining (Radeon 7850).
OK, my PC is on 24/7 anyway (I'm a torrentor), so for me, this power increase costs me about £3.24 extra per month, and gains me 0.05BTC per 5 days (.3BTC per month) - or £22 at todays exchange rate.
So if you have your PC on 24/7 anyway, then GPU mining with a decent mid-range Radeon is definitely worth it, but running it purely to mine, then not really, unless you have a really awesome GPU, or crossfire set up.

Just get a job at a power plant. They probably wouldn't care about a few watts...
