Still worth mining?

Hi, I have access to 4x R9 290s, which I think would all fit in my mobo.

Is it still worth it to mine?

If so, any pointer to where to get started would be welcome.
 
they will cook hugging each other... if you have decent priced power of course its worth it but if you have them all hugging each other don't bother
 
Undervolt the crap out of them. Max hash is not your friend, max hash per watt is.

Are you buying these or are you getting them free/cheap?

It's your friend if you have cheap power. Then you might as well go hash/$. God I miss the days of $12/mh. :(
 
All depends if you are paying more for eletricity. Some people with cheaper power it is still profitable.

$12/mh per day

Yeah, don't put 290s next to each other, references or not. I did this and temps shot up to uncomfortabe levels (93C) even in my cold basement for non-reference cards. I also tried reference 290s next to each other, temps went up but not as bad. All in an open-air case too. There is still profit to be made assuming your power cost is $0.10 or lower but your ROI will be a good 6 months if not a year assuming difficulty goes up and coin value keeps coming down.
 
Thanks a lot for the replies.

The thing is I am moving soon, and one of the potential flats comes with "free" electricity included in the rent :eek:

Well, I am starting a HW online retail store here in the UK, and I got 290Xs for about $550.00 USD. Is that a good price?

The idea would be to not sell a few of them and use them to try out mining, as long as I can recoup the price I paid for them ;)

What about using those PCIe extension thingies I see around the internets? Does that help? I mean 290Xs are insane hot.

Yeah, if you use risers (ribbons or USB) you can place the cards better, getting more air to them. This is all you need. The good USB risers used to be $20 each but have come down to $10-14 or so. Look through the "Pics of your mining rig" thread to see how they work. MSRP for a 290x in the US is $549 so $555 isn't too bad, although with the flood of people selling them on ebay, I'm sure they can be had for much closer to $500 or lower, used of course.

Grab some powered USB risers. You can spread out the cards, and take the power load off your motherboard. Win-win.

I had a friend living in a place with "Free" power. Trust me, It's free till they get the first power bill :)

Then it's still free. But your rent is OUTRAGEOUS. Haha.

Since when can a landlord change rent legally on a signed lease assuming no clauses that specify usage up to x kwh?

Thats msrp for a 290x. TBH at this point I'd be leery of sitting on a pile of them because "asic fear" is going to make a lot of people dump cards pretty soon and prices are already dropping. That's US market though, no idea what the UK market is like but I'd keep an eye on it.

You definitely need powered risers for them. There's really no other way to keep them from ingesting each others' hot air otherwise. Look at the rig pics thread.

If you want to get into it a little cheaper make a rig of $90 4GB R7 240s and mine scrypt-jane. Must be 4GB though. Cheap to start out and more future proof than vanilla scrypt mining. There's guys out there running 50 of them.

Interesting choice 4GB R7 240s.

What about GTX 750ti. I heard those are good for mining, but not sure.
