I'm new to serious mining (I've tinkered with GPU mining on my GTX 1060 just for fun but I know it's not profitable) and I'm considering building a cheap rig with used GPUs. I have absolutely no clue what I should buy; should I buy a more expensive recent GPU or an older GPU that is really cheap, or somewhere in between? Are there specific models you look for when building your used rigs? What should I buy as a newb to serious mining?

I'm interested in mining ethereum or vertcoin since I've read they are profitable on GPUs. I don't want to spend too much on this but the rig needs to pay for itself within a year. Electricity here is about 10c per kwh (USD)

Another thing I'm concerned with is heat. It seems to be one of the factors that isn't mentioned too much. If the rig is putting out a ton of heat, it will raise the electricity usage from the AC. Where do you put your rigs to avoid this?

Thanks

The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

Probably you should look in the Altcoin Mining forum for advice.

I asked for this to be sent to alt coins.

I think your gtx 1060  may be good enough to mine ETH

here is a nvidia thread

I mine alt coins with https://simplemining.net I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Whoops, didn't even think that this might not be the place to discuss altcoin mining. I don't really want to burn my 1060 mining ethereum, I use this PC for college and gaming, but if it's viable to mine overnight then I'll look into it.

I'm still interested in cheap used GPUs though.

Edit: another question, should I mine ethereum or ethereum classic?

You can probably find a R7 370 for under $100.  They get 14-15Mh mining eth.

I'm strongly considering building a 2 GPU RX 480 rig for $663. Here's the rig on PCP: http://pcpartpicker.com/list/nw7h3F

If my calculations are correct it will pay for itself in 183 days, excluding electricity cost.

Does the hardware look OK? That motherboard is kindof iffy but it seems to work for a few other people.

I haven't looked into powered risers yet though, which I know I will need to.

Looks like that board only has 5 PCI-e slots.  The Asrock H97 Anniversary is a popular mining rig motherboard and has 6 PCI-e slots.
Ribbon risers can work but they are more troublesome, especially the longer (20-25cm) ones.

If your electricity is cheap, get a used 290X or a 290. they can achieve 30MH or more with overclock and they are fairly cheap. the best watt/MH option would be RX 470/480.
