OTOY Forums

I currently have a one GTX 970 and am considering upgrading my GPU setup. The two thoughts I have are:

1. Buy two 980 Ti cards. I've heard the 980 Ti is wonderful.

2. Go all out and buy one Titan X.

What do you guys think? What would be the best decision to get maximum performance from Octane?

2*980Ti is definitelly going to be 90% faster than single TitanX but TitanX has double amount of VRAM so it all depends on what kind of scenes you plan to work and how much VRAM is "enough" for your projects.

If you get 980Ti(s), by all means get EVGA Hybrids, if you can.. and your case has exhaust ports to accommodate them... You will not be sorry.

why not thinking of 2x 1080 instead of 2x 980 Ti?

I got 2 machines here, 4 GTX 980 Ti on air and 3 GTX 980 Ti hybrid (from EVGA). Those hybrids are really insane, my air ones were running very very hot so I stuffed hybrids in between and they go to insane speeds at super low temps, they even help cool down the air cooled cards! So definately get the hybrids

I have one 980 Ti reference with hybrid cooler and thinking to hybrid cooling the two other cards, if i stack the hybrids, does the temps stay cool?
Cause like you said, the evga 980 ti hybrdis are awesome! Last year i had one original from evga, i sold it and gets two 980 ti amp extreme, and now i just got an swapped one from reference to hybrid with an overclocked bios.

Yes you can, but you need to have a really big case that fits the radiators!

Here is my setup on PC 1:


By doing hybrid - air - hybrid - air they all stay very cool, the hybrid ones even help cool down the air cards...

Oh yeah, to the OP: the hybrids go to their max of 1340 MHz effortlessly while still being like 50-55C here. The limit here is actually the allowed TDP, not voltage or anything else! So I had all air cards before and I had problems with the thermal throttling all the time, especially annoying in Octane. Now all those problems are gone. Get hybrids! Best cooling solution you can get, it's simply plug and play, and if it somehow breaks you can get warranty from EVGA, instead of EVGA telling you 'you messed up your own custom water loop'! Also no maintenance required whatsoever, they come in 1 piece, you screw them in there and you're done.

Phantom107 very nice setup! Totally agree with you, the AIO cooling solution, imo is the best, water cooling performance via plug and play...
With AIO we can have an entire system water cooled (cpu and gpu) instantly, it's cheaper than diy water cooling and versatile! We can switch the build any time without breaking the entire water loop cause there is no general loop.
Andrewmcmurry if you consider a used second hand 980 ti it's the best option right now.
