Question about VRAM - Page 2

But again, with a single 780Ti you probably won't even get playable FPS in most games when more than 3GB has been filled up. So it wouldn't have helped much even if you got a 6GB 780Ti.

If it is an issue of budget, get a 780 and save the rest for a later upgrade to a 900 series card in 2 years. No one can tell what the situation will be within 3/4 years so it is impossible to give an accurate timeline as to when 3GB will become obsolete.

Is it not a good idea to get a 780 or 780 Ti now and then get a second one two or three years from now and use SLI?

Definitely no. In SLI, VRAM will still remain the same and while you will have a lot of GPU horsepower, you will be limited by VRAM. If you get a 6GB 780Ti, that would be a different story altogether. In that case you can opt for SLI later on.

Like I said, if you can get another 780Ti in 2 years, then you can spend that money on a 900 series card too, which will definitely be more suited to the requirements of games of that time. Besides, when the time comes, you can learn about whether going SLI will give you more performance or getting a single new card will. You can only make an educated decision at that time when all the relevant info is available. It is not possible to accurately know the best upgrade path right now.

Under what circumstances does the 780 Ti substantially outperform the 780? I only use one monitor at 1080p, so I'm wondering if I'd notice that much of an FPS increase with the 780 Ti vs. the 780.

I can't comment on the 'substantially' part, but a 780Ti definitely outperforms a 780 in any and every situation. It will depend a lot on what kind of overclock you can get out of the card.

But if you're concerned about value, I think a 780 is a better value than a 780Ti. At 1080p, you will be able to almost max out every game with a well overclocked 780. Again, AMD's R9 290 is probably even a better value option (if you can find them at $400, which is what the actual retail price is supposed to be).

As for noticing the FPS increase, I think the higher the FPS the harder it is to understand the difference between two different numbers of FPS. For example it would be much more difficult to differentiate between 60 and 70 FPS than it would be between 15 and 25 FPS. But since these cards will keep FPS high in most cases, I think it would be a bit hard to notice the difference.

Also, settings which make the game unplayable with a 780 will most likely make it unplayable with a 780Ti as well.

If you want the absolute best, go for the 780Ti and if you want value for money I think the 780 is the way to go.

(I'm considering the prices to be $500 for 780 and $700 for 780Ti. I don't know what the actual prices are right now. Please accept my apologies.)

I just ran GPUz while playing Skyrim (without any of my graphics mods installed) and it says my GPU load was 99% and VRAM usage was 1861. Does that mean my 2GB GTX 670 is insufficient for this game, especially once I install high res texture mods?

That means your GPU is just enough for the game and the settings you were running at the time (assuming your FPS was okay). If you install any graphics mods, you'll run out of VRAM quick.

99% usage means your GPU is the bottleneck. This is normal for most games, but it means that you'd have to turn graphics down to get higher FPS then current... and that if you install graphics mods, your FPS is definitely going down.

If you got a new GPU, it's likely you would still get 99% usage, but with a much higher FPS. This means you have room to install graphics mods or turn settings up, and still get the same or better FPS then you were before.

Assuming we are talking about vram usage as in what programs like afterburner show (which is usually considered by many people to be allocation and not actual usage) I've had my 770 reach over 2300MB on Battlefield 4 while still averaging above 60fps.
