Question about NVIDIA GTX 780 SLI

#11DiehardFFv2Posted 7/31/2013 10:15:44 AM
You're better off going SLI 760's and using the money saved to upgrade again sooner than you are going with SLI 780's or even just a single one. You will have better performance overall and you will save money too.

That is also a nice idea, how much sooner in your opinion? with 760s I'll be upgrading with the new ones

Before buy the PC i was thinking of getting a GTX690 over Titan with the pc, and then i heard that GTX780 is coming and will out performs the GTX 690 with 2 way sli so i thought why not wait and get the 3x3=6gb gfx cards which will out perform GTX690 that out performs Titan in most games.


Actually, the amount of vram doesn't have much to do with performance right now unless you get into extreme textures, which only really happens with mods and even then nothing even gets close to 3GB.

And you don't get 6GB of vram with SLI on 3GB cards, you still have the 3GB and they just work together (I guess that's the easiest way to explain it). They aren't additive like that. If you had two 3GB 780s in SLI you'd still have 3GB of useable vram. Which is more than enough by the way.

And the reason it works like that is because of the way SLI works. Both cards must work together to render the same frame, so they must have the same information loaded into VRAM.

hmm good info, and i do use a lot of mods, specially with skyrim, also make them..

Hows the Gtx 670 in your opinion, i read that GTX 670 with 2 way sli is better than one gtx 690

Gtx780 is obsolete already, i thought it was just came out a couple of months or may be 3 months ago.

This is what I mean by "obsolete." This is a video of a Titan, running Tomb Raider 2013 at max settings @ 1080p. I apologize for the quality of the video, but for some reason YouTube compressed it to 720p. In any case, you can see the the frame rate fluctuating between 26-30fps. Btw, that's on a Titan clocked at 1124Mhz, so you could extrapolate what SLI 780 results would be like. As I said, current high end cards can already be considered obsolete when attempting to "max" some of the most demanding games released in 2013. If I were a betting man, I'd say that by 2015 you'll need to start turning down settings like AA on your SLI 780 rig in order to keep frame rates between 40-60fps in more demanding games.

My 770 keeps this game at a constant 60fps on ultra settings with TressFX and max shadows, it only goes down to 40 in cutscenes, but is doesn't affect my gameplay, and I haven't overclocked.

Even the Cheapest 670 still costs ~70 dollars more than a 760 and only offers ~5% performance if even that. SLI 760's are where it's at when common sense is involved right now.

Your 770 doesn't get those fps when running the same settings in that video.

I see, my SC Titan drops as low as ~28fps in certain cutscenes at Ultimate settings, i.e, Ultra+TressFX+FXAA minus maximum shadows. The settings I used in the video would absolutely obliterate my frame rates in some cutscenes. I'm talking between 10-15fps low...
