witch would be the best opition ?buy another gtx 680 4gbor upgrade to a gtx 1070 or 1080would it even be worth getting a 1070/1080 over 2 680s for cycles and vray rendering and 1080p gaming ?
>GPU renderingokay bud
depends on the cuda cores.search whatever card has most cuda cores
>>544723cycles and vray support cuda
>>544723>hurr durr crap gpu render
>>544724That's not a very good idea. Some older cards have more cuda cores than current models, yet they are obviously significantly slower.I switched from a 780 (2304 cores) to a 1070 (1920 cores), and it cut my render times in FStorm in half.
what cards are good for rendering? I got a gtx 960 2gb it does alright. what's the ideal?
680 is equivalent to a 1050ti, so putting them in SLI is not going to get you near the same performance as a 1070 or 1080.
>>544801I dun goofed. Have 980, bought used 780 because COOOOOORES. It does seem to render almost fast as the 980 at least.
>>544731CUDA OUT OF MEMORY
>>544721those are gaming cards. sell them and buy a pair of quadro M4000's, a pair of quadro M4000's costs less than a M5000 and is faster. M6000 is like 5 grand anyways. you can later on add a maxwell Tesla compute card if you need yet faster spedz.
>Not having one computer for gaming and one or two for rendering.That's my goal one day.
>>546862save up a thousand bucks and you'll be good.
>>546835Quadros aren't really any faster for GPU rendering than the generation equivalent GeForce or Titan cards. For example current Pascal cards:>Titan X 12GB - $1,200>Quadro P6000 24GB - $5,000The extra vram is nice if you're rendering huge scenes, but that price/performance makes no sense. And a Quadro M4000 is not even half as fast as a 980 Ti in octanebench. Nor do you get any better interactive viewport performance from Quadros.>>544721Upgrade to a 1070. You'll want the extra vram for GPU rendering and the 1070 is the price/performance sweet spot for 8GB cards.
