what does extra memory on a gpu do?

[Meteora]

Hey guys i was wondering what does extra memory a gpu does i was looking at Evga 760 2g superclocked but then i saw the nvidia 760 4gb. Does the extra memory make a difference in performance?

Allows for more textures to be loaded into the buffer. If you're gaming at 1080p, 2gb will be fine. But if you're gaming at like 1440p+ you'll want 4gb

Not really unless you have triple monitors or have games with a lot of complicated graphics or programs that use alot of VRAM

If you're playing at resolutions above 1200p, then 4GB is recommended

Well it helps a lot with high resolutions such as 1440P and triple monitors.

it only nets you performance when it can take advantage of the amount of memory.  but having more memory does not necessarily equate to better frames-per-second performance.

Injecting 2-4k Tetxures into Skyrim to make it look a lot better, so that texture memory... gets used moreso using 2-4k Textures than using 1-2K textures.

Once your at your memory limit and your game or settings used actually overflow the amount you have, this can lead to stutters/frame hiccups and other random slowdowns.

Skyrim (because of Texture mods) actually can get you maxing your GPU easily, most games released do not go so hard on your memory system and 2-3GB of vram is fine.

 Also another question, does 2 gpu's running each monitor better than 1 gpu with more memory?
