I agree with the view that we should not pay more than MSRP for the cards. One way to look at risk is called "value at risk". Taking the worst case scenario, how much money will you lose (example, crypto all crashing 80% tomorrow).

Those who went with 480/580 at $400 USD will find their cards worth $100. Even if their GPU can make $6 a day for 66 day ROI, their value at risk is 75% of their upfront cost.


Those who went with 1080ti at $700, but make $7 a day has a 100 day ROI. However if crypto crashes 80% tomorrow, their cards are worth $600 at least. That's only 14% of their upfront cost, value at risk is way lower.


If a person can put $10K value at risk. He can buy $71K worth of 1080tis, or he can buy $13.3K worth of 580s. For the same amount of money RISKED (not in upfront capital), he gets much much more hash.

After doing some calculation, including rig costs and estimating difficulty of resale, 1080ti are the best. 1070s has to $350 or less for me to consider. 1080tis do suffer a bit more in depreciation however.

That's beaufiullll. What PSU are you using? I have two of these exact model and 6 1070 asus.

I'm using the Evga 1200P2, running 5 cards per rig. Using a 2x 8pin to dual 6+2 pin splitter per rig. 80% TDP, roughly 1125W at the wall per rig.

damn thats looking nice, are you on 110V with those?  i ask as
i am building for max-hash type ti rigs like that (tho mine are classic open frame, not rack, and yours look great!)
but i fear popping breaker on startup with x6 ti, may i ask why you did 5? mine are five also (for breaker reason)
i am using 1600 watt hercules (only thing i could find with enough 8x2 pins for x6 ti's)

Clean setup! Cheesy

i tried 5 cards mining zcash on a 1000 watt psu with bad results, best i can do is 4 1080 ti with 70'percent powerlim
for 640 or so per card or the rig reboots , really need to get my hansds on some 4k psus but the picos i have only do the one cpu pinout anyways

TOTALLY.  my theory is it pulls the full TDP on startup and thats what does it Sad
cause i thought: ok i can TDP limit them, it will be NP, but NOPE Sad STARTUP does it haha.

WE NEED FINKSY :/ those 2880 jabberwoks would do SO well (tho i'm not 100% that they are 110v as well as 220)

yes i think you are right, with 5 GPU it would freeze and reboot immediately, but with 4 i could get it past startup and then mining although at slower than the 750 hash on zcash i should be getting.

On my meter I see a total of 4 amps at 240 v for the rig so they are definitely not using the full TDP once they start mining.

but i have to keep Powerlimit low or the rig reboots again.  The issue is now i have 2 1080 ti's with no home.

On 240V with these. Each circuit has 20A breakers (4480W limit), but my power splitter only handles 13A (3120W). 2 rigs are on a single circuit now, drawing a total of 2300W, plenty of leeway. I need to find some power splitters that can handle 20A.

I really wanted 6x 1080ti per rig, but 1600W power supplies were nowhere to be found last month, hence I had to go 1200W psu and 5 per rig. In the future, I hope to replace them with 1600W Evga T2 psu and go 6 per rig, and use these 1200P2 psu for 6x Vega or Volta 150-200W TDP cards.

Vega will cost 1000 or more why do you think it will be a better buy than the 1080 ti at $700 ?  , I saw a T2 1600 psu for sale for like $600 , didnt these used to cost $400 ?

I am able to get the 1600 T2 for $430 USD now, ordered 6 and they are arriving mid july. It's $401 on Amazon too. But yeah last month it was $600, passed up those and got 1200P2 for $260 insted.

The Vega frontier edition is $1000 and has roughly the same Tflops as a 1080ti. The Rx vega gaming edition will be much cheaper and should have the same Tflops as it is the same chip, just less ram. Not buying FE edition, but the gaming rx version launching end july.


If it is priced lower than a 1080ti, it is simply more Tflops per dollar which will help it for compute bound algo, like Lbry, Skein etc. It then comes down to power efficiency. If it hashes at 700h/s in zcash at 200W just like the 1080ti, it is an instant buy for me because I believe there will be driver and miner software optimization in the future.

Vega is coming in smaller chips later this year or early next year and eventually will trickle down to mid range. Miner devs will optimize for it.

If mining benchmarks for the current $1000 cards are bad, I guess I'll grab more 1080tis

Hashing algos doesn't need Tflops. (floating point operations)

LBRY on AMD cards is slow. The opensource LBRY implementation used to do less than 100MHASH on a rx 480. Is there a faster miner out there?

Intersting , i saw a benchmark for the $1000 vega on eth at like 35 mhs, I might hold out for the gaming versions too
thanks for the info

If it is priced lower than a 1080ti, it is simply more Tflops per dollar which will help it for compute bound algo, like Lbry, Skein etc. It then comes down to power efficiency. If it hashes at 700h/s in zcash at 200W just like the 1080ti, it is an instant buy for me because I believe there will be driver and miner software optimization in the future.

Hashing algos doesn't need Tflops. (floating point operations)

LBRY on AMD cards is slow. The opensource LBRY implementation used to do less than 100MHASH on a rx 480. Is there a faster miner out there?

Ah I mean "compute horsepower" (assuming it scales linearly with tflops, not sure what's the right term). The above algos are just example, I have never experimented with AMD cards outside of eth and zcash.

Intersting , i saw a benchmark for the $1000 vega on eth at like 35 mhs, I might hold out for the gaming versions too
thanks for the info

Vega is realy bad dude, here are some initial benchmarks for FE edition ( for workstations ):

Time Spy Graphics = 6785 pts
Fire Strike Ultra Graphics = 5091 pts
Doom Vulkan 4K Ultra @ 55-65 FPS
The Witcher 3 @ 28-35 FPS at 4K Hairworks on / 41-42 FPS with Hairworks off (80 C running the game)
Troubles OCing past 1650 MHz with the blower
Tried to OC HBM, starts at 945 MHz, managed 960 MHz stable and at 980 MHz it got too hot
Tester says you won't be able to OC without additional cooling, thermal throttling (80-85 C)
Tester put 2x 80 mm fans to help (open air case) and it was down to 75 C
Tester doesn't think it will touch the 1080 Ti performance-wise, only 1070-1080s
Mining: 30-35 MH/s
Cinebench R15 OpenGL: 97.39 FPS
Card operate at 1348-1528 MHz in gaming mode during The Witcher 3 testing

Maybe the RX edition will be better, because this is way below 1080 for gaming standards, not to mention 35Mh/s in mining lolz

ya thats what i heard, a 1080ti is STILL pulling better benches then their new "flex" cards:  Frontier
honestly i think they were too slow on these new chips, and those new "mining cards" are a joke (tho nvidias may be better) 125 watt and 25mh/s? Pfft

I'm using the Evga 1200P2, running 5 cards per rig. Using a 2x 8pin to dual 6+2 pin splitter per rig. 80% TDP, roughly 1125W at the wall per rig.

damn thats looking nice, are you on 110V with those?  i ask as
i am building for max-hash type ti rigs like that (tho mine are classic open frame, not rack, and yours look great!)
but i fear popping breaker on startup with x6 ti, may i ask why you did 5? mine are five also (for breaker reason)
i am using 1600 watt hercules (only thing i could find with enough 8x2 pins for x6 ti's)

Clean setup! Cheesy



On 240V with these. Each circuit has 20A breakers (4480W limit), but my power splitter only handles 13A (3120W). 2 rigs are on a single circuit now, drawing a total of 2300W, plenty of leeway. I need to find some power splitters that can handle 20A.

I really wanted 6x 1080ti per rig, but 1600W power supplies were nowhere to be found last month, hence I had to go 1200W psu and 5 per rig. In the future, I hope to replace them with 1600W Evga T2 psu and go 6 per rig, and use these 1200P2 psu for 6x Vega or Volta 150-200W TDP cards.

I went 20A 110, and fully wish I had wired for 220. I use 2 1000w Evga PSUs with an add2psu connection (so I dont have splice wires and can resell PSUs later if needed). I have 6 per board running with headroom for growth - last I saw on vega is that it was power hungry so I wanted headroom. Have zero issues, except the occasional second PSU will not power off immediately (1 sec delay) - but who wants to power down anyways.

HEAT in the cords is an issue to watch.

There are no softfork...The chokepoint created by the transition to Segwit will kill some coins, but CitiBank is already holding ZEC, DOGE and DGB, waiting for the hardfork and the dual transaction failure. Spread the message!

NO need to spam!

I keep asking this and get no response.. Where do you recommend minding DGB?
