So perhaps this is a bit off topic, but you guys seem like a knowledge group. Are the 750 ti's the most power efficient of the of the Maxwell cards? Thanks.
It greatly depends on where you live; for me the 970s are the best choice by far even if I only go for 4 x 970 per rig, but of course I also add 2 x 750 Ti.
While a 6 card 750 Ti rig looks great on paper, you can't really disregard the price of the whole PC itself (mb+cpu+memory+hdd+psu) which all adds up, disrupting the efficiency/ROI of a 6x750Ti rig. But of course YMMV.
ill be building a 6 x gigabyte 980ti g1 miner very shortly ( when the funds allow ) and will have the results in comparison to the 6 x gigabyte 750ti oc lp miner ...
this should give an indication ( hashrate also ) of how efficient these two machines are ... admittedly - ccminer-spmod - it will be a huge hashrate difference - but power efficiency will be the question with this - not hashrate ...
i am actually hardpressed to believe that the 6 x gigabyte 750ti oc lp miner would not be more efficient than the 6 x gigabyte 980ti g1 system ... even if all the computer power consumption is taken into effect ...
obviously this is not using the 970 as you specified - but i dont think thefarm will be upgraded to the 970 card - so i couldnt test that anyway ...

As I said it depends on how much you can get your hands on certain cards. To me for example a 980 Ti rig (or even just a 980 non-Ti rig) would be suicidal. And then again putting 6 of those cards into one rig would require a very pricey PSU unless you don't care about RMA time or resell value, or don't mind using two PSUs which I personally refuse to do.
In my personal case 960s are sligthly more efficient than 970s and 750 Ti's but I decided to only use 2 types of cards in order to simplify things so I'm only buying 970s and 750 Ti's until Pascal comes along which allows me to know the efficiency of the cards depending on the algo without having to calculate it. More cards would just complicate things.
understood ...
the psu count IS a pain in the backside - especially due to the fact that not is it more power - but a lot more space required to run them ...
thefarm itself being upgraded to the 980ti g1 is highly unlikely ... ONE miner for testing and high level hashing - possibly ...
i too am waiting on the pascal chips / architecture to hit the market - but even then - the cost would be iitially a great deal until they settle in the market and drop to a price for general use ...
so you think the 960 cards are better value? ... ill look into this and see what we can get them for here in australia ...
tanx bathrobehero ...
btw - i have not ever really looked heavily into the resale value of any of the cards - as you can never really get back anywhere near what was originally paid for them ... i usually average it out at less than half of the original cost for resale - IF i ever resell them ...
