Will the dual-core Pentium G3258 somehow limit performance (not gaming) of dual RX 470 or 480 in crossfireX on my GA-Z97X-Gaming 7 or other crossfire capable motherboard? I'm looking for the cheapest CPU that I can under-clock to save energy for mining.

First, you don't SLI or crossfire cards to mine. They run as separate cards with total number of processing cores available to the mining software.

That said, GPU mining is deal

ASIC mining or group pool cloud mining are the only two viable options now and that's even barely.

Eeeeerm, it might bottleneck the RX 480 quite a bit, it will be minimal with the 470 though, dunno why you'd want to use it on your main rig.
Don't bother mining, unless you have serious Xeon hardware you won't find a single bitcoin, its becoming harder and harder to mine, you'd be better off doing it with your 4790k due to the higher performance, regardless mining is a waste of time and will just stress your hardware.

So I could just add an RX 470 to my main rig and use both the GTX 1060 and RX 470 to pool mine ether? Or do they still have to be the same card?

No you can't.
With Nvidia you can only SLI the 1070 and up for a start since it is disabled on the lower cards due to the poor yields, and AMD only allow crossfire between their own cards.
Give up on mining, it is a pointless investment of money, please don't waste your hard earned cash on this. :(

People have been saying the same thing for years. Have you seen the price of ETH lately? Will there not continue to be new blockchains created to mine? Besides, I just want to buy 2 or 3 RX 470s to mine for about 6 months to a year, which at the rate it's going now will yield a profit.

In addition to the price of the mining rig, have you considered the cost of electricity? Also, with cryptocoin mining the amount of compute power to finish a block progressively increases, meaning that even though the value of the currency may be increasing over time, you'll also be earning currency at a slowing rate.

True. Which is why it makes sense to tell anyone wanting to do it not to do it.

So making a ROI and a small profit (or are you saying there is no profit to be made?), and then being able to sell your hardware is a bigger waste of time and resources than buying and playing Call of Duty and/or the next latest game?

I think it would be interesting to do nonetheless.

Yes, you're not going to make a ROI unless you get extremely lucky over the course of 2-3 years+, even then it will be very minimal. Take into account the power used during that time, the resources committed and what else you could have spent that money on and it isn't worth it.
If you wanted to get in on Bitcoin mining, you're 5 years too late unfortunately.

That is exactly what people are saying. It's one thing if you already want to build a rig for gaming and want to do a bit of mining on the side (assuming you pay reasonable electricity rates). Building a dedicated mining rig expecting to make money on the other hand hasn't really been a good idea in years...

Okay so mining is dead. But I'm still not sure my question has been answered.



My 4790K is underclocked to 2.4GHz right now and uses about 10W of power at .089V sitting idle while my GTX 1060 is overclocked and getting 22MH/s. Can you explain how the Pentium would bottleneck a 480 but not a 470 if it isn't required to do anything? I was wondering if it would limit the PCIE lanes (especially if I wanted to use 2 GPUs), would this be the case?

Oh, sorry, I forgot we were still talking about mining here, not gaming.
There won't be a bottleneck since they both work individually, but this is really a waste of time imo, and I SERIOUSLY don't recommend undertaking this procedure, seems like a good waste of money to me, but if its what you want to do I can't stop you.
