I heard the memory buses on the 670/680 are too slow to benefit from 4GB of vram...is there any truth to this?

I heard this too, it seems to be the achilles heel of these new cards.

At the moment for my purposes at 1080p, BF3 with 4x MSAA enabled, seems to use up to 1.9GB vram. So if a game released before the card is using that much, it will be interesting to see the results when newer games like BF4 and Crysis 3 arrive, plus the next generation console ports. Kind of wish I would of went with a 7970, especially as I am considering bumping up the rez when I have the cash. It seems strange that the 690 also only has 2GB, which must severely limit it on a 1440p+ monitor. I guess some people will disagree, but I wouldn't want to worry about whether or not I could run AA or mods and a high rez, especially with an almost €1000 card....

Asides that though, the 670's performance is amazing. I am very pleased with mine smile.gif

Just asking, IF you are playing a demanding games like BF3, MOH, etc. Of course you will see/feel some Dip FPS from your card (like a ton of explosion, etc), how many frames DIP which you can accept/call it as a 'playable'?

I'm asking just for 670 owners. smile.gif

I prefer running with vsync enabled to prevent screen tearing, but notice the stuttering in dips below 50fps, which has everything to do wtih the admittedly ridiculous amount of GPU overkill in my build at the resolution I'm at.

Strangely, though, L.A. Noire is fixed at 30fps, and I am perfectly okay with it and actually like it that way.

Why not fix your FPS through MSI afterburner?

 

I fixed mine to 59 and I have no screen tearing and no Vsync.

I had concerns about this, which was why I went at 2Gb for now. I will more than likely upgrade to a card (or cards) with a wider bus if I move up to 1600p down the road. Would like to stay at 16:10, if I can.

I've hit 2Gb with modded Crysis at 1200p, so I know I'm getting close.

I'm going to try this -- thank you for the suggestion. I admit I'm a bit naive about the whole monitor thing, and just thought that vsync was a requirement to stop it -- but I'm already running AB so this will be easy to test.

Card looks great and performs well. Only real issues I have with it are the temperatures, and fan noise. It was a real treat having an ASUS 7850 before. I could OC it to 1050/1450, leave it on 20% fan speed, and run Furmark for 30 minutes, and my max temp was 67C. smile.gif
I don't even want to try to do that for this card, it's 72C on 41% fan speed. frown.gif


Try removing the stock paste with alcohol coated wipe and apply Coollaboratory Liquid Ultra or Pro to it. I used Ultra on my 670 FTW and I got 20c drops in temperature under max load, oced to 1400mhz core and 1.213v. That using a custom fan curve that maxes out at 70% when over 70c (which NEVER happens)

The 4gb 670 is not a waste for over 1080p res gaming
