If i decide to go EVGA 780Ti SC with a blower cooler, i should get more performance overall.
Oh well, i have 14 days to make up my mind..
BTW, when i'm already maxed out @ 1150mhz(boost) it feels like i won't be getting much higher with Skyn3t's bios, i would only be able to over volt 0.03V or 30mV. What do you think?
So you must have a DCUII card, as the reference (one blower cooler) is classic PCB shared with Titan/780/780Ti, if you get the reference 780Ti you'll get the same VRM's, inheriting the same [R33] inductor problems! Normally no, unless your card is restricted by PT limit (hitting 106% all the time you game or bench, the card will down clock) then the modded bios will free it and will get higher clocks!

Have a read from one of my articles:"Exactly what happens depends on how excess the power is. It may be a sustained cooking. In this case, the MOSFET gets hot enough to literally unsolder itself. Much of the MOSFET heating at high currents is in the leads - which can quite easily unsolder themselves without the MOSFET failing! If the heat is generated in the chip, then it will get hot - but its maximum temperature is usually not silicon-restricted, but restricted by the fabrication. The silicon chip is bonded to the substrate by soft solder and it is quite easy to melt this and have it ooze between the epoxy and the metal of the body, forming solder droplets! Excess heat leads to short circuit! Usually, a MOSFET will fail short first. This is because excessive heat will, by diffusion, mix the dopants enough to create a good conductor instead of the p-n or n-p barriers that were there originally. Often, the gate oxide will be taken into the diffusion, too, causing a short between all three terminals.
Only if the short circuit current after this first mode of failure is high enough to blow the bond wires or the entire transistor, there is an open circuit."

So I can't find people blowing cards from folding but mining seems to be the key word, I have no idea how they'd differ though (don't do mining myself). No warnings at EVGA and they've got a folding section/team nor anything in the folding area here.
From folding i got only one report and was a Titan, not a 780Ti but the burn was in the exactly same place as the dead mining cards, the [R33] memory inductor!

After some reserch I realised that the only review`s version cards have higher clocks bios version than reatilers cards, so in my opinion this MSI policy is strange and bit unfair towards customers . My question is whether you can easily flash consumer bios version 980/1046mhz version....2C up to reviewing bios...30 version 1020/1085mhz..Please for your advice and sorry for my english witch is not perfrect but I`ve tried my best.
Normally some "sponsored" reviewers get golden samples to review that go higher clocks than the retail cards, that's why i don't trust any site for any review, just go there to see the overall picture!
I rather trust in the OCN members with their feedback!
Any card you buy from any brand could be a bad card or a good card, its always a gamble, the silicon lottery!
Yes its easy to flash a bios, you have EZ3flash in my SIG and my guide on how to flash!
If your name implies your language, feel free to PM me in spanish if you run into problems as i speak a few languages!
