Can BitCoin mining still be profitable with nice GPUs?

Not with bitcoins but it can be with litecoins.

Don't bother. The amount you'll spend in electricity to power your rig will vastly exceed anything you reap from mining. The difficulty factor has risen so high that GPU mining hasn't been feasible for quite some time now.

do you like to gamble?

as i see it; BC & it's alternatives are a volatile market. one that usually involves a whole lot of waiting for when exchange is at an all time high to cash in, which was the case several weeks ago. most of the time though you're not gonna gain much, all while wasting away your electricity bills. if you got the patience and got lucky, you may see yourself getting enough to get a lamborghini. otherwise, you may see yourself quitting in frustration, thousands of dollars spent on a mining PC + electricity bills.

again, it's a gamble. do you like to gamble?

It's really the same process. I've only used guiminer and simply switching pool would change what coins are being mined.

I just answered a different thread and gave a picture of what I make in a week.

This is profitable for me for the following reasons:
1)bought the equipment before the popularity sky rocketed(must get GPUs at or under $275 each. They are out there but it takes time to find them now)
2)This is big-free electricity-plugged into power at my work, enables me to deduct costs due to the fact that its an expense and I own the business. You may want to start an LLC so you can deduct this expense. Make mining a business. Sorry just read that you have free power so this can be a money maker for you.
3)Got in early

Dont let the above deter you. This is an extremely fun hobby and can be very rewarding. I would get in now. Oh and you should not mine BTCs you should mine alt coins to sell for BTCs. That is the only way to make BTCs through GPU mining that is still profitable.

Get into a pool that mines multiple coins. The pool mines whatever coin will get the most BTC when sold at that instant in time. Then when you have at least 1 coin send it to an exchange to sell. This is all done automatically once you setup your parameters and payout addresses in the pool. Its all pretty amazing stuff. Hope this helps you.
