GTX 1080 ... which is recommended...
 
For TF; or LL; maybe for ECM; or P-1?

I'm hoping in general it is the same card.

When I look on [url]www.newegg.ca[/url] (and exclude several out of stock) I see prices (CAN$) between $930 and $1,112 (not a big gap).

I have a note from a 5 months ago (from some mersenne.ca specs) that this was a leader then:

ASUS ROG STRIX GeForce® GTX 1080 TI 11GB OC Edition VR Ready 5K HD Gaming HDMI DisplayPort DVI Overclocked PC Graphics Card" (P/N ROG-STRIX-GTX1080TI-O11G-GAMING).

.... OR ....

is GTX-1080 yesterdays news :)

All of them has only DP performance at 1/32 of SP, so they will not be super for LL. They are so fast though, so they are still semi-decent I think? But it might be considered a "waste" using them for LL and "wasting" that high SP performance.

My GTX 1060, running CUDALucas, is a bit faster than 2 i7-6700K cores, running p95. The 1060 is over twice as fast as the GTX 460, with the same, or less, power consumption. All these devices are overclocked. All are running Cat 3 DCs, fairly close to each other.

So much better suited for TF...that where I'd most likely use it anyway.

If for TF is this a top card?

The GTX 1080 is excellent for TF. The 1080 Ti would be better (and a lot more expensive), but the 1080 is awesome.

And due to the GTX 1070 being better for Ethereum mining, the GTX 1080 actually has better price/performance for TF right now.

Yes, at ~ 8.2 TLOPS it is only topped in the "normal" graphic cards category by 1080 Ti at 10.6 TFLOPS, Titan X at 10.1 and Titan Xp at 10.8:

and by a few of the crazy Tesla's:

The 1080 is quite good for TF, but also good, more than decent, for LL.
See Jame's [URL="http://www.mersenne.ca/cudalucas.php?model=684"]LL table[/URL], it is just a bit below a Titan, and it is like two 580s put together, for a fraction of power. And it is actually the first at LL by "JVR" value, which means that, with the electricity price in your area, you will be on the "profit side" in less than a year.

Edit, and as the winter comes, are you heating your house with electricity? Then buy few more... hehe... Oh sorry, you didn't know the winter is coming... in that part of the world is always winter... :razz:

Edit 2: Hey James, BTW, you sort that table by price... lexicographic on 4 characters. Since the price of some cards went into $10k, that cards appear between cards with price $900 and cards with price $1100. Please fix it.

Yarrr :chappy:, eager to see the $1M GPUs... Maybe you know something we do not know :razz:
Thanks for fixing it.

I'm also in the market for a new GPU for:
- TF
- The occasional DoubleCheck
- Racing games (Project Cars, F1 2016)
- Roleplay/lounge games (Elder Scrolls, Kerbal Space Program)

I'd like to get an ASUS card again, since I've had several years of good experience with them (a GTX470, GTX580, two HD7950 and a ROG Matrix 280X)

Preferably I'd like to order it on a reliable hardware webshop in the Netherlands, that have them in store (Coolblue.nl and Azerty come to mind first), even if that means paying 10 or 20 euro extra.

This would be the prices:

ASUS ROG STRIX GTX 1060 - €389
[URL]https://tweakers.net/pricewatch/567301/asus-rog-strix-gtx1060-o6g-gaming.html[/URL]

ASUS ROG STRIX GTX 1070 - €519
[URL]https://tweakers.net/pricewatch/547969/asus-rog-strix-gtx1070-o8g-gaming.html[/URL]

ASUS ROG STRIX GTX 1080 - €633
[URL]https://tweakers.net/pricewatch/564833/asus-rog-strix-gtx1080-a8g-gaming.html[/URL]

ASUS ROG STRIX GTX 1080ti - €839
[URL]https://tweakers.net/pricewatch/749945/asus-rog-strix-gtx1080ti-11g-gaming.html[/URL]

Expected TF GHzdays/d (from [URL]http://www.mersenne.ca/mfaktc.php[/URL])
GTX1060 - 459
GTX1070 - 689
GTX1080 - 980
GTX1080ti - 1263

CUDA cores
GTX1060 - 1280
GTX1070 - 1920
GTX1080 - 2560
GTX1080ti - 3584

Memory Bandwidth
GTX1060 - 192 GB/s
GTX1070 - 256 GB/s
GTX1080 - 320 GB/s
GTX1080ti - 484 GB/s

TDP (W)
GTX1060 - 120
GTX1070 - 150
GTX1080 - 180
GTX1080ti - 250

GHzdayd / TDP(W)
GTX1060 - 3.8
GTX1070 - 4.6
GTX1080 - 5.4
GTX1080ti - 5.1

Energy costs per kWh (in €)
0.06280 + 0.12257 + 0.00895 = 0.19432 (at night 23:00-07:00)
0.08069 + 0.12257 + 0.00895 = 0.21221 (rest of the day)
(0.19432* 8 hours + 0.21221 * 16hours) / 24 hours = 0.206246

2 year running cost electricity (TDP/1000*0.206246*24*365*2years)
GTX1060 - 433.61
GTX1070 - 542.02
GTX1080 - 650.42
GTX1080ti - 903.36
Already owned:
ASUS HD7950 - 505.88
ASUS GTX580 - 881.68

GHzdays per day / Total Cost (initial cost+ 2y electricity)
GTX1060 - 459 / (389 + 433.61) = 0.558
GTX1070 - 689 / (519 + 542.02) = 0.649
GTX1080 - 980 / (633 + 650.42) = [B]0.763[/B]
GTX1080ti - 1263 / (839 + 903.36) = 0.725
Already owned:
ASUS HD7950 - 308 / (0+ 505.88) = 0.609
ASUS GTX580 - 433 / (0 + 881.68) = 0.491

So the GTX1060 is not really a good option, since my already owned HD7950 outperforms it in terms of GHzdays/€ . I've stopped running the GTX580 for some time now and these numbers support that decision. The GTX1080 has the best performance/€ on paper followed by the GTX1080ti. I probably don't really need the performance of a 1080(ti) for the games I play, but at least I can now justify spending the extra money :razz: .
