GTX 680 2GB vs 4GB worth the wait?

Poll Results: Should a PC builder wanting high-resolutions (2560x1440) refresh rates over 60FPS in high-VRAM applications (Battlefield 3) go with a GTX 680 2GB or wait for a 4GB?

Hi guys

I am building a computer with a 2560x1440 display refreshing at 100Hz. It will be a work-from-home and gaming machine. I am aware that the 2GB reference GTX 680's can handle these requirements now, but do you believe there will ever be a practical benefit to having a 4GB version, including the addition of vapor chamber cooling? Basically, will 4GB of VRAM on the GTX 680 ever make a significant difference over 2GB in high-resolution, high-VRAM-usage applications, or will the GTX 680 still be limited by the 256-bit memory bandwidth in these types of applications? What is the expected release date of ANY 4GB GTX 680? I am needing a GPU ASAP to work from home, but I want to wait for a 4GB revision if it's coming very soon (ie by the end of April '12).

Thanks so much,
Jon

Honestly, if you are only using one screen I think you could get away with 2GB... 4GBs is more of a nvidia surround thing.

Battlefield 3 will start to approach 2GB of VRAM at 1080p on max settings. At your resolution, I'd imagine it will get very close if not hit that 2GB mark. Then there's the fact that in future games more VRAM could be necessary. We buy top of the lines cards for their future-proof-ness (fun word), so why not get the card that suits your needs more?

I vote wait based on your needs.

BF3 is coded inefficiently regarding VRAM. basically, if it has tons available, it will use tons. i happen to play at 1080p with only 1GB of vram. i can actually do ultra w/ 2x msaa with playable framerates (45ish average).

the point is, just because it will fill the vram, doesn't mean it needs it. hitting a vram wall is much more apparent than hitting a cpu bottleneck or any other bottleneck because frames will go from playable to horrid in one swoop.

in any case, if you don't plan on doing surround, then yes, 2gb will be plenty.

but isn't that just because bf3 doesnt properly handle textures (like not clearing unused ones out of the VRAM)

Actually, I saw some benchmarks today @1600p, which is a bit bigger then your screen, 7970 3GB vs. 680 2GB... and the extra VRAM was making a difference in some games. So I would say wait or get 7970...

lol... doesn't really matter much at this point. Back then 1.5GB 580GTX was like beast. People kept on being brainwashed by the VRAM marketing saying it is never enough to run it... The matter on benchmark 3GB vs 2GB is vague most likely it is something else than VRAM.

Never come close to even 1.25gb of Vram on BF3. And I play with all settings on ultra. 2xMSAA, high postprocess, SSAO, 85FOV, 75Hz 1080p.... I'm typically around 1.00-1.20GB
post #9 of 169
I would think if would be enough for now. Just remember how people had said 1GB was plenty for all 1080p though, and that surely isn't enough for today's game. I'm thinking of waiting for 4gb or the 685/780 so I can have a card to last me easily through college.
post #10 of 169
I'm also waiting on the 4gb for the 1600p I'm using

Even if I dont need or need the 4gb, for the sake that I want a 4gb Ill get my hands on one or a couple of those cards, same debate about Vram always ..... and this also happened with Ram, when guys had 8gb and everyone bashing that 4gb is enough, screw that ! 16gb is the new 4gb it costs $100 anyway now LOL.

So get the 4gb and forget about the feeling of "what if" I had the other one instead of the normal 2gb.
