Triple SLI GTX780....is it worth it?

The guy I bought from is in Portugal on eBay with zero feedback. Paid via PayPal so if it is too good to be true, I'll get my money back. I saw that one also and thought the story was just a bit too fishy. At least the guy I've bought from has communicated well, his stories ring true and his listing was just 2 GTX780 brand new. End of. Lol.

Guess we'll see by the end of the week if I have them in my possession. My ideal scenario was two asus Gtx780 so that what I think I'll still with and move on the EVGA after testing it for noise and cooling.

I wish you the best of luck and I hope you get your cards :)

the guy stated that 2x780 was too powerfull for him, so he went for a single 770, I don't trust this.

You can nearly always use the extra GPU power and if you find your self in the position that it is causing a problem then you can disable sli in seconds.

I would rather have too much than too little.
 
I also think 1 is more than enough for him.

In my case I would need 2 to run the games that I play on my 3 monitors setup... for now my 2x7950 are doing a good job (3 would be ideal)
 
I'm going to keep the two Asus in SLI. It future proofs me and saves me money. Plus, the SLI performance gains are huge even though I may not see them now but, when the next gen of AMD boards and CPU are released with PCIE3 then I probably would, or the next level of games where this hardware is actually utilised. Maybe I'll cross over to Intel after being an AMD user for 13 years.

I don't play game though so all this talk about games is very secondary. I need a multi monitor setup that will handle the most graphic intensive design and development program's.

Rather than having the the 3xSLI GTX780, I think you would benefit more from some semi-decent level graphic card, and invest more on faster CPU and more high speed system memory instead? :confused:

I honestly don't see the benefit of 3xSLI GTX780 if you are not gaming.

Can't believe you bought so many high-end cards and thought the GPU RAM added up like that!

Fair play though

And if I'm using mult monitor?

And the extra ram is used anyway in SLI. One card processes either one frame or half a frame wile the other one process the next frame or the other half, then its all sent to the card with the link to the monitor and is displayed so I really don't understand why people are thinking that having two cards doesn't give you more memory and processing power.

Lets say if you get 2x 2GB cards and SLI/crossfire with 1x 1GB card, you will end with only 1GB of video memory, because the extra 1GB on the 2GB cards will not be used.

I think it's been established one is going. I was thinking one was always going to go unless three was some miracle setup that was über powerful.

in SLI or Crossfire it's a NO.

All cards will have the same buffer, it is mirroring images...

doesn't matter if it if multi or single monitor.

Yeah, it's limited by the cards buffer, as in how much data the card can get out of it right? If you're asking for two cards worth of data to go through one, then it essentially halves the buffer but....one card is sorting out 50% of the image or another frame while the one card is sending data through the buffer. So, the master card is sending data while the slave card is or is only using a proportion of the buffer etc if it is split framing the image.

Both cards still process data at max capacity, depending on how well the code is written in the drivers for the application etc.

That's my understanding of it from what I read through nvidia.

Nope there's no master/slave relationship regarding VRAM. Both cards utilize their VRAM in precisely duplicate manner.

SLI and CrossfireX usually use AFR (alternate frame rendering) which makes your gpus draw frames in turns, let's say one draws all the odd frames and the other all the even frames.

To be able to do that you must have a copy of everything readily available to the GPUs in questions, for a GPU to access VRAM that does not directly belong to itself it would be very hard to implement software wise and especially bandwidth wise, - you would need a very very fast link to provide textures that are only available on another GPU VRAM on that system.

When I configure two graphics cards in SLI mode, do the graphics cards work together to create double the memory size?

"No. In SLI mode, each graphics card uses its own frame buffer memory to render a 3D application. The operating system will report a graphics card frame buffer memory size that is found on a single graphics board."

I'd keep all three mate. Let me just tell you, the ladies love 'em!

I've just got one, and it's worked wonders for me.



*In reality - showing my girlfriend my new PC*
Me: OMG look at that 780! It's beautiful! :eek:

Her: :o I like the colour of it

Don't think it would work for me

If I said to a lady friend "let me show you my Titan" I would probably get a slap.:D

I spent £800 on new stuff last september and all i got was " I like the case with the see through thingy so you can see the lights"

I never even bought a new case, i used the one i had previously, She obviously doesn't pay attention at all.
