What Gpu system to build?

[Kerem]

Guys this is mainly about performance. Excuse me if i am posting this the wrong section.

At the moment i'm running low on my one gtx780

I want to consider my options on building a new mid-range gpu system. I will be needing a lot of vram. So i'm thinking i need 2 Titans ?

Any tips? Also for the psu i'm more than happy to hear what you have to say...

As I Know, 780=titan, only changes the ram size.

I dont know about the 9xx series but people usually recommend the 780 as the best card now.

So maybe the solution is more 780 in the box.

hi,

if You need speed & more vRAM - there are three options, here's a list from best value, all of them are gk110:

1. 780 (6gb) - might be hard to find, needs extra space to breathe as there are no reference design coolers for 6Gigers (shines under water)

2. TitanZ - Dual GPU card, for ~1500$ gives a good value too, but it getting hard to find those..- bad thing is that it requires 4 slots - 3 for placing (though cooler is 2,5 slot), but extra slot is needed for it to work propperlly & don't throttle down.

3. last but not least, Titan Black - offers least of value, but has reference coolers (that works slightly better in tight multiGPU builds),

+ You can find original Titans that still offer good value & might be in used market for very good price as some gamers happily change them into Maxwell based cards because of all optimizations nvidia is making that is useful for them..

However for GPU rendering I would not go for Maxwell line, at least until we are going to see something new from nVidia. Hard to say when, but feeling is in month or two =) so if You are not in a hurry might be worth to wait..

cheers

P.S. TitanZ has one good thing to offer : if You watercool with let's say EK's kit You can shrink the card to dual slot - that gives You very dense power house - two GPUs in the same place that is usually occupied by one (aircooled GPU), but You need to take into account watercooling expenses(rads, fans, pumps, fittings, blocks, etc)..

P.P.S. knowing what You own (detail by detail) would give a bit better feel of what could be done, budget is another factor..

guys thank you for the comments. ı will really look into each thing you said. I'd love to just put another 780 and get on with my life but there's not enough vram.. when i try to render with passes in dimensions of 8k 9k...

I own a 3 year old gigabyte motherboard and i only have one more slot. 24ram and 12 core i7. the case is big enough it is a corsair c70. If not, finding a 780 with 6gb would be really nice for me. But it is my company who's asking i get a report together on how can they invest in my computer. So the money is not an issue but off course not buying the needs with it would be stupid.

ı just want to make sure vram is my only issue on not being able render huge dimensions. so it is...

that huge output resolution is going to eat like 2GB+ of vRAM on Your GPU, so at this scale getting bigger cards (at least 6GB) is wise move if You work with complex scenes.

Be sure not to use screen plugged into cards You're rendering with as that will cut 300MB at least from You total pool of vRAM..- have a dedicated card for that

so if You take into account final resolutions, then You're left to play with something like ~4GB for the scene (geometry, textures =) when using 6GB cards.

Ok so two more questions pops up!

one- can i say if i just get one more gtx 780 with 3gigs. does that mean i have a total of 6 gigs to work with?

IF SO, how can i manage my future second card to render only. I only have 2 monitors so eventually there will be nothing plugged in the second one?

many thanks for your enlightment.

yeah You can power monitors with one card' but do rendering with other, that will be without any plugged monitors.

However if You have 3 & 6 GPU, but want to render on both of them at the same time, You'll be limmited to 3GB as scene & all it's assets should fit into all cards (vram of all GPU participating in rendering).

that is tremendous! will finish it after this deadline..
