Have any SLI 980 owners here recently upgraded to a 1080 and was it worth it?

I'm looking to SLI my 980 because the HSF is damaged and I can't RMA it, but it works fine. Basically I wont get much by selling it used, so I'm looking towards the SLI upgrade path instead of the 1080.
I'd like to know if microstutter and issues of that nature are still a big hindrance.

I don't have any microstutter issues at all and haven't had any since my days of running EVGA GTX-570 HD s/c boards in dual SLI.

I decided to wait for the Ti cards. I still run 1440p and I continue to see 140+ FPS on the games I play. That may change at the end of this year,early next, but i really wanted to get at least 2 years out of my 2 STRIX cards. Unless you are running 4k or mutli displays I would wait. But since you only have one 980 i would try to see if you can find a decent used 980 and run SLI until the Ti cards or your needs increase.

On a 2nd note, i have not experienced stutter since my HD5xxx (xFire) cards way back in the day. Although, i did have a friend with 4 titans that struggled with the issue, disabling 1 or 2 of the cards tended to fix the problem (not sure, other than bench queen/rendering, he spent the $4k). I have not heard much of this issue with 2x cards. I really think this is why Nvidia does not want to deal with the more than 2 GPU set ups.

If i can get 2.5 years out of the 980s I will be happy with the new investment into 2xTi cards. I will really have to see how my performance is on the next few new games. I think once the high Hz 4k displays start to come out the need will increase, I am still on the fence about VR.

I own an SC and can't use the overboost feature. It was unlocked on my 780 and 780TI, but not on this 980.
Currently at 1530MHz on water and would love to push the voltage a bit more to get some higher clocks with the huge cooling headroom i have.
Any ideas?

Nope, it's greyed out. I can select Overvolt and KBoost, but not Overboost.

The EVGA SC is a Maxwell card and not a Kepler. +87 is also to high on the volts.

So Overboost is not supported with Maxwell?
Also, why is +87 too much? It's what i need to be stable at 1530. Was planning to custom BIOS and try to hit 1600...
Everything i've ever seen/read regarding OCing suggests that +87 is fine...

Edit: i see you are at +127 with 12mV. That's impressive... I have ASIC 77.1% and around 45C under max load - and yet i can't even hit +127 without crashing in games. Silicone lottery or am i missing something?

Edit: stable at +12 atm

+87 is not too much voltage as long as your temperatures are reasonable and not high enough to cause throttling. 1500 MHz is a respectable OC for a GTX-980 with a stock factory VBIOS. I would be careful modding your BIOS unless you are watercooling. That's just my personal opinion as I found the factory cooling solution on my MSI GTX-980 Gaming 4G were barely sufficient keeping my boards cool at 1500 MHz with +250 on the Memory Clock.

My 980 has a Kraken G10 + H90. Temps are around 30C at idle at and 50ish under load - loads of room for more voltage.
Only problem i've found is in finding a good BIOS. I've found one here, but i'm not completely convinced just yet. There's not half as much online about BIOS modding the 980 compared to what there was about BIOS modding the 780 i had.

Anyhow, the temps are great, and i'd be happy to see 1600MHz. I got to 1550 in heaven and it crashed after a few seconds (not instantly), so that's a good sign that with a few more mV i might be able to hit a nice 1600/500 (8GHz mem) OC. I might consider grabbing some small heatsinks for the VRMs/VRAM - but the card does have a midplate so things might be alright?

I'd love to hear from anyone who BIOS hacked their SC 980. smile.gif

Edit: How much does upping the V from 1.2 to 1.3 actually affect longevity? Seeing as people OC their CPUs and add more than 0.1V, I can't imagine it's all that much considering temps are okay.
