I've currently heavily modded skyrim with textures using the Skyrim Mod Combiner. However because of the large amount of textures in use skyrim crashes when the VRAM usage hits around the 3gb mark. My current card (7970 matrix platinum) is really glitchy and artifacts on the slightest overclock anyway so I was looking to upgrade preferably to the nvidia side due to the amount of issues I've had in the past with ATI cards. Now the card I was looking at getting to replace it was a gtx 780 ghz edition from gigabyte. that card however has the same amount of vram and bus size or whatever its called. Will gtx 780 have any difference in regards to vram usage or will it fill up at exactly the same rate?
looking forward to any feedback on this,
cheers.

The VRAM usage will be almost EXACTLY the same.

Also, you don't actually know WHY the game crashes. It may or may not be directly related to VRAM usage. It's probably the mods themselves conflicting somewhere not specifically a memory issue.

It's also certain the performance will plummet with all those mods.

Anyway, why not just focus on removing mods that are too demanding on GPU and VRAM and sort out your mod issues rather than just buying a slightly faster graphics card?

according to ASUS GPU tweak my memory usage is spiking up in skyrim to around 2.8-2.9GB of VRAM usage so I'm fairly certain its VRAM usage as there is no crash message or delay or anything its very much instantaneous. You're right though I think I have gone overboard with my textures I'm changing back to the old combined texture pack I was using. It seems to run ok though when I have it on my overclocked settings (which are shaky to say the least). The card I have gets lines across the screens and sometimes randomly artifacts on stock with no apparent cause. some times it'll go for hours without a hitch and other times it'll just be all over the place. So I'm definitely planning on doing an upgrade at some point.
Cheers for the response photon, I appreciate it.

On graphics cards:

1) If you have artifact issues, then consider RMA'ing the card if still under Warranty.

2) I often recommend the EVGA GTX780 967MHz base model to people (about $500 USD).

3) You might wish to wait for the new NVidia cards. They've done a really great job. The first card with the new GPU architecture oddly is a GTX750Ti, though I expect the high-end ones will be GTX880 etc.

The power efficiency is simply amazing.

Unfortunately RMAing didn't result in anything first time I tried as they didn't find any fault after benchmarking it for a couple of hours supposedly. What do you suppose the waiting time will be before the 880 will be released? I noticed they're coming out with 6gb 780 ti so I can't imagine it'll be overly soon right?
