Hello guys!

I'm seriously thinking about buying a new graphic card, to make animations with Octane + C4D.

I currently have a GTX 770 4GB (http://www.amazon.com/Gigabyte-GDDR5-4G ... B00CU9GOAO.

It seems at lot of people around here have GTX Titans, so my first choice would be to go for it.

My PSU is a Dark Power Pro 10 650W, can it handle such a beast ?

Also, I heard about the Nvidia Quadros (like this one : http://www.amazon.com/NVIDIA-Quadro-K50 ... rds=quadro), is it a better investment ?

And finally, if I buy one of these, do I still need my GTX 770 ?

Thanks!

My tuppence worth....

Quadro isn't as good for things like Octane (I'm fairly sure).

Regarding Titan only difference between it and a 780Ti is the price, and the fact that it has double the Vram. Vram is only an issue if you plan to have big scenes, with lots of textures. A lot of people here are very happy with their 780s. Also, there is supposed to be a 6GB 780 on the way (don't know what price that is though).

I myself have two Titans (one of them a Black).

I personally (unless you want to use it for super games, would keep your 770 and have be what drives your displays.

Not sure about the PSU, but I would think it would handle one Titan, but perhaps not a titan and your 770

to summarise,

Quadro or Tegra are best where more precise calculation are needed.

Octane is faster on single precision cards like geforce series and its cost far less for the same rendering speed !

If you could buy a new card, choose more CUDA cores and Higher frequency and if you need high poly count scene you could choose more than 2Gb Vram (or as I do: make tiled rendering) because Ram is what cost much on Cards, secondly to benefit from these higher vram you need a PC With more Ram (about 3 to 4 times the vram = 16Gb for a 4Gb card ) because virtual memory would leaks most of the transfert time to the GPU specially if you make animations.

Hope this could help in your choice

Thank a lot for your enlightened answers guys!

I think I'll go for the GTX Titan, it should be a nice addition to my workstation.

I've got 32gigs of RAM, so if I understand well, they're actually not so useful but should become handy when I'll have a Titan ?

About the PSU, I ran a quick test (http://www.bequiet.com/fr/psucalculator/quick) with my config + GTX Titan, and as results, it returned me 3 PSU from 630W to 700W.

I presume my actual 650W can handle both cards, right ?

If not what kind of problem can I encounter ?

Last question, a little bit off-thread, but my workstation is a Hackintosh, so I'm wondering if someone is already running this kind of card on a similar build without problem.

That's still a lot of questions, sorry

And thanks!

Off-topic but what kind of case and mobo can handle 4 GTX Titans ??

I'm amazed by the Octane 2.0 demo !

Off-topic but what kind of case and mobo can handle 4 GTX Titans ??

If you have an intel socket 2011 processor, I personally would chose the Asus Rampage IV Extreme. It can host 64 GB of RAM and has 4 PCIE 16 x slots, and if I am not wrong, they can all be used at 16x if SLI/Crosswire is not enabled (to be verified).

hi Bolos.

You power supply should be more than enough feeding single Titan/780 as these draw 250W under load. Some guys are runing 780 with 450W PSU (but it very much depends what other parts You're using). If it's good PSU I would even try running two 780s on 650-700W PSU (but You might be short on connections =)

as for platform for 4cards, as Roubal mentioned You can go 2011 or cheaper with 1150/1155 that has PLX chips =) so it really depends for what You're building the platform & what other task You're looking' to throw for it =) if CPU power is not needed I would definatelly stay away from 2011 & choose any other with iGPU support so I would power screen & leave GPUs for computation only.

as for Hackintosh - I've seen some guys using those here, so simply take a look around the forum, or do some search here =) I if You will not find answers already written simply drop PM for them. Personally I have no experience with this topic, but I know that some things might be tricky there =)

as for demo, Yeah, it's amazing =) & the best piece is that all this scene was render with something like 1.4Gb of vRam on GPU (if I remember good =) & the render time wasn't that long either..

Waiting for gtx 780 ti 6 gb

A bit late to, but thank you all for your answers!

Do you guys think Titans prices will drop down until the release of Octane 2 ?

I don't really need such hardware right now, but if it's only to save a few bucks, I'd better spend them right now and instead save time.

I'd surely have to find the answer myself, as "few bucks" and "time" are not really unbiased, but your thoughts about it might help me to find it!

Thanks!

PS : Still no release date for Octane 2 ?
