GPU Upgrade: GTX 780 - how much of a difference between 3GB and 6GB?

#21JonWood007Posted 7/27/2014 3:30:57 PM
I'd wait for 800 series, but I'd go for 6 GB if possible. Mainly because a lot of games use insane kinds of vram nowadays. I still have to turn textures down on some games with a 2 GB 760 superclocked. I'd say if you want something that will last for a while you'll want at least 4 GB VRAM.

I have two 780 Tis in SLI and play at 2560x1440. The only game I've run into ram issues with is Watch Dogs and that game is terrible. No other game has had issues with vram. I also don't do much in the sense of super high resolution texture mods and such though.

If you game at 1920x1080 and don't plan to SLI, there's no reason to pay the extra money for the 6GB version. The gpu will run out of processing power before it runs out of ram for about 98% of games. If you plan to SLI them and play at higher resolutions, then 6GB may make some sense.

There's rumors that the 880 will be announced on August 13th, I'd wait til then just in case. If you must get a card now go with the 3gb model. Make sure you get an evga model so you can use the step-up program to trade for an 880 if released by October.

I own the 6gb.

The difference is 3gb more Vram.


You're welcome.

Depends on your resolution OP. For the most part you won't see any difference between the two, (besides having less money in your wallet) on screens that are below 1440p. I think the 780 6gb still struggles @ that res anyways (I am not 100% sure on that) You are better off waiting till the 800 series releases.

I know that itch, you want it so bad. But I still run a 5870 in my HTPC and it games just fine with the newer releases with some minor tweaking to the settings. I am sure a 480 will do fine for the next few months.

It hasn't been since the days when it was measured in MB.

Since "next gen" consoles and gratuitously bad optimization of textures. There are already games out there that slow down with 2 GB VRAM.

Just a few years ago, people were claiming 1GB was enough. A few years prior to that, 512MB was enough, etc etc.

If the price difference is small, always go for the model with higher VRAM.

No, games don't slow down with 2GB of VRAM, it causes no performance loss. You can check out benchmarks of the 770 GTX 4gb vs 2gb and see this.
