This is crazy. I ordered fifteen (15) cards from Newegg.com for $249.99/ea and that was in December!. The crappy part is how I had to order them in groups of three. Wait 48hrs. Order three more, etc. I did the BIOS mod and I'm getting 29.8 MH/s per card average for the Samsungs, 28.7 Hynix, and 24.66 with the crappy Elpida memory. Thank God that almost all were Samsung!

That's why I say the Nitro+ 8GB are the most sought after. I have 2 of them and they are both getting 31MH/s after BIOS mods with zero memory errors in HWInfo.

Where and what are you mining?

Yeah, way over paid. I have a total of 6 RX 580's and 1 570. I never paid over $309 per card (most were at $299, the 570 was $229). I have a mix of XFX, Asus, MSI and PowerColor.  I'm getting right at or over 30 Mh/s on each card dual mining. I have a little more tweaking left to do on each to make sure the power and speed are optimal, but I'm pretty close right now.

At $500 a card, your ROI is going to be right at 5 months plus however long it will take you to pay off the rest of the system - so you're probably talking a 6 month ROI. Buying the cards at the right price, and you'll have an ROI of half that.

Alright guys, I am returning them. I just ordered a mixture of 1080's and 1070 ti's that I paid less then the other RX 580's.

1080s are only good if you're getting them for pretty much the same price as 1070 Ti's. If they're noticeably more expensive than 1070 Tis then they're not worth it. GDDR5x memory is not as good as the regular GDDR5 for some algos (there's been quite a few very profitable Neoscrypt coins lately, and 1070 Ti is faster than 1080 on those).

I got them for around $500 each with the tax.

much better deal

Cancel 1080s, get all 1070ti's.

[clems]

From by test / mod bios Saphir RX 580 Hynix/Samsung/Micron are ~ 31MH/s for ~100W for ETH / For ETN ~ 880H/s ~80W

It can be better but with my OC/Strap no error and pretty stable.

Curious as to why?

Probably for the reasons I mentioned in the previous post. GDDR5x has currently no advantages for mining over the regular GDDR5 (except some very moderate power savings). The compute difference between 1070 Ti and 1080 is only about ~5% (based on the number of cuda cores). You'll lose a lot more than 5% in the algos that are memory dependent (that's ETH and Neoscrypt for the most part). ETH rarely makes sense to mine on nvidia cards, but Neoscrypt is all the rage right now. And it's faster on 1070 Ti.

Thanks for the clarification. I appreciate it. Does it make sense to keep two of the RX's with the Nvidias to have an 8 card rig or because I paid too much, it wouldn't.

Are you in the US? If you are, there's a few RX 580 cards available from newegg for $350 each.
https://www.newegg.com/Product/Product.aspx?Item=N82E16814202280&cm_re=rx_580-_-14-202-280-_-Product — Nitro 580/8 for $360.
https://www.newegg.com/Product/Product.aspx?Item=N82E16814150794&cm_re=rx_580-_-14-150-794-_-Product — XFX 580/8 for $330.
https://www.newegg.com/Product/Product.aspx?Item=N82E16814131713&cm_re=rx_580-_-14-131-713-_-Product — Red Devil 580/8 for $350.

Just return the overpriced stuff you bought for $500 each and buy some of these if you still want to own some Polaris cards. It's still not cheap, but a lot better than $500. I've got all of these and both Sapphire and Powercolor have good coolers. XFX is not so good but still fine.
