VRAM/GDDR Question.

Having a 768mb GTX 460 and thinking of upgrading to a 1.5GB+ card, I have been wondering about when the benefits of more memory apply.

I've always seen people say it helps with higher resolutions, if so, wouldn't that be because you use more RAM loading up larger textures? please correct me if not.

And if that's true, wouldn't you basically benefit from more VRAM /WHENEVER/ your game is using more RAM in general, not solely from using more RAM via a higher resolution setting?

I ask this because playing SC2 at 1920x1080 I use 1.7 GB of RAM, this seems to eat up quite a lot of RAM, and it's not like it's graphically demanding, so as a rule of thumb, do you benefit from more VRAM if the games you play typically eat up a ton of RAM?
 
with a card with 1Gb or more is ideal for people that game at 1080 or 1200 or greater.
Have more Vram can in some cases get better performance at average resolutions like 1440x900 or similar, but then the card with more Vram pulls away at higher resolutions.

Can i ask where you got 1.7GB of ram useage from (task manager)?

Your probably looking system memory not VRAM.
768mb is poor though. U need a min of 1gb for dx11 and Rez 1080p+ IMHO

Wayne 1 or 2 charts will do :)

My GTX460 768mb is a superb card never seen 70% Vram usage yet. 810Mhz core 1620Mhz shaders 800Mhz mem, fantastic 55c on load.
 
Use msi afterburner and it will show proper gpu use, memory usage etc, with a single gtx 470 i was seeing 800+ mb memory use, bfbc2 and moh being two games, 1920x1200.
