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

#1ChrazidPosted 7/27/2014 2:06:44 PM
Upgrading GPU very shortly, possibly even will order today - so, I'm looking at upgrading FROM a GTX 470 TO a GTX 780.

I notice there is 2 'versions', however, a 3GB and a 6GB - with the 6GB not being very much higher cost-wise, how much of a difference in both performance AND power consumption is there between the 2?

Are you sure you don't want to wait? The 780 is over a year old already, and the GTX 880 is coming out in October or November.

You won't need the 6gb almost guaranteed, that level of vram should only be necessary if you're modding a ridiculous amount at very high resolutions. The power usage difference should be negligible really, though.

I keep hearing mixed things about the 800 series coming "soon" and being delayed until spring 2015, and can't really seem to find any confirmation either way

as an owner of the 3gb 780, I say go for the 6gb.

newer games at 1920x1200 with graphical mods sometimes max out my vram, and skyrim regularly maxes the vram, resulting in crashes.

IMO, it's not a dealbreaker, but something to be aware of.

They're not delayed until 2015, they're confirmed for this year:

If the price difference is marginal, definitely go for the 6GB model.

VRAM above 3GB is, at this point in time, largely a waste unless you plan to be gaming at 4K or plan to be using a ton of very-high-resource graphical mods.

And if you plan to be doing one of those, you are far better off waiting for the 800 series. Even if it gets delayed into next year, it's still better to wait, as all signs are pointing to the 800 series cards being substantially faster than the 700s and significantly cheaper (in terms of the cost of 'current top end card').

Skyrim is just incredibly poorly optimized. Try the texture optimizer to help reduce vram related crashes.

I don't know what you're talking about. I have a 3GB 780 and play at 1920x1200 and use the official high resolution texture pack and have zero issues.
