I have that exact monitor with 3 7970s, and at 2560x1440 maxed out with 4x MSAA in BF3, my Mem usage is 6GB, meaning 2GB of memory is used per card. So basically you're right at the threshold of the 680's capabilities at that resolution. As far as being future proof... who knows though.

Wait is the best option IMO, the 4gb will be used in a near future. Also if you play skyrim with lot's of mod, you surely will reach the 2gb cap (pure speculation, im not a user of mods look at my rig frown.gif ). I guess that waiting for the 4gb wont hurt anyone and you will end with a better card for sure

My GTX 680 borrows 2GB memory from the motherboard..

so i guess i technically have 4gb

i dont play or plan to even try battlefield 3..
but it does run crysis 2 in 2560x1440 with everything on ultra, smoothly. smile.gif

SkyRim 5760 with texture pack added 680 2GB ram no problem.gif

 

 

Oh well, no one seems to listen to facts and evidence. As I've said before it's already been proven 2G is plenty. Many will say otherwise but they don't have any evidence. In fact the opposite stares them in the face all over the internet, but we all know nothing trumps emotional hype. ( advertising as one astute gentleman put it)

The 465 your sig lists as you owning has 1280 ram not 2048 or 3096.

 

Perhaps try a 2G model with a much faster core, and get back to us.

Or look at the chart above which is conclusive in Skyrim w/ the texture pack added at triple monitor resolution.

The not enough ram cutoff point is not 1920X and is higher than 5760x1200.


" While gaming at 2560x1600 was fantastic, we wanted to push the video card to its limits, and so next we configured an NV Surround triple-display configuration and gamed on three displays from the single GeForce GTX 680. We wanted to be able to run at the native resolution of 5760x1200 and compare the performance to the Radeon HD 7970. We figured if any resolution is going to show the advantages of AMD's memory capacity and memory bandwidth edge it would be 5760x1200. We were absolutely surprised that the GeForce GTX 680 had no trouble keeping pace with the Radeon HD 7970 at 5760x1200. We thought this is the resolution we might see the GTX 680 bottleneck, but to our surprise no bottlenecks were experienced. "

http://www.hardocp.com/article/2012/03/22/nvidia_kepler_gpu_geforce_gtx_680_video_card_review/14

 

 

Note the 7970's extra and useless 1G of ram doesn't prevent the 0 frames in Skyrim and doesn't prevent it's loss to the 680 @ 5760X1200

 

http://www.hardocp.com/article/2012/03/22/nvidia_kepler_gpu_geforce_gtx_680_video_card_review/11

 

 

 

BF3 same resolution same cards:

 " We found that both the Radeon HD 7970 and GeForce GTX 680 were playable at 5760x1200 with "Ultra" settings and FXAA, as long as we reduced Ambient Occlusion to SSAO. With the default, and highest quality option, HBAO enabled performance was sluggish and laggy on both video cards at this resolution. HBAO caused a severe performance penalty. When we reduced the quality down to SSAO, performance picked up and the game was playable. There is a slight performance edge towards the GTX 680."

 

So, there's no more room for ram to improve anything, the cores are already eaten up, the 7970 core fails before the 680, slightly...

 

 

In spite of all that, better PCB setups, improved VRM and voltage control, besides the apparently false peace of mind 4GB gives, is plenty of reason to buy the 4GB models.

 You will likely get a better overclock, have superior cooling performance, better voltage control, an even quieter card setup, etc.

 There are real reasons other than emotional feelings coupled with unlikely future scenarios to buy 4GB models.

Yeah, OP, I would say that if you are playing games such as BF3 or Skyrim, then try to wait a couple of months, seeing as it will be difficult to even get a 2gb 680 for a couple of months, so you might as well go for the 4gb. Also, if at some point you decide to go for surround, or some ridiculous game comes out and uses much more than 2gb, then you might regret it. Just my 2cents.gif
