(I am not sure if this is the right forum, but I hope moderators just move this to the right one)

Do you guys know bit coin miners using GPU? I wanna try out some of these. I heard there was a CPU miner too. Are these bit coin miners legit? If yes, can you please give me link of nice miners?

guiminer (.org) and guiminer (.net) are the ones that I discovered, but I am not sure if these are legit also.

From other threads it seems that bit mining is no longer profitable. This has resulted in a price drop with R9 290 and 290X GPUs - the most popular used for bitmining

dont waste your time and money on this.bitcoins where nice to mine at first.algorithms have become harder.
the money you will spend on electricty is not worth it.having your pc to run on full load and consume tons of watts so you can make a bitcoin in a year.

only with asic you might be able to get profit.

Yes, you want to get the 290 or 290X and mine a newer coin, like the Vertcoin. It is immune to the ASIC machines that killed the bit coin.

or 750 ti which has great performance/W which is what you're really looking for in a mining machine
(make sure you mine on the scrypt algorithm as ASICs are dominating SHA-256)

nvidia is not suitsble for mining a r9280x has 600 megahashes and a nvidia titan not over 150 megahashes.
ASICs can have 600 gigahashes and consume nearly nothing compared to a gpu.to be able to get this hashrate form gpu you will need to spent quite a lot.

Actually, Maxwell is significantly better in terms of power consumption than Kepler. That gets it there.

SHA hashrates can't be compared to Scrypt ones.

There is new miner software for Nvidea called cudaminer. With it I am getting 500K hashes with scrypt on my Titan overclocked to 1019GHz and 250K hashes on scrypt-N

And the scrypt is far harder than SHA-256 so you cannot compare the speeds. Apples and oranges.

Accually I was talking about efficiency and scypt mining
the 750ti achieves 300 khash/s at 60W which is 5 khash/(sW)
the 280X by comparison consumes 257W bitmining and achieves ~750khash/s which makes less than ~3khash/(sW)

Bought 3x 750 ti's the other day just cause I was bored and dropped them into some random machines that run all the time anyways. Doing around 290 khash/s per card and going by usage on a corsair axi psu I have they are using around 80 watts at high load with mild overclock.

edit: They are quiet as can be as well. At max load they are hitting around 60-62 degrees Celcius. Fan speed even at that level I have louder case fans. Mining some litecoins as well if that helps.

Exactly my point, thank you

Err, OK, that's the second time someone selected a solution here.

EDIT: And it's not the OP.
