So, buying my new cards in less than two weeks time, and wondering if i should get a pair of 2gb FTW 670s or a pair of 4GB cards with reference board. I will be watercooling so the better heatsink of the FTW isnt an issue, but the bigger board has better power delivery and can probably overclock better, as well as the fact that watercooled 670s would look ridiculous on a EATX board.

I will be running my three screens in surround (resolution 3510x1920 bezel corrected)

I am currently running my 6990 on this setup and am using insane amounts of vram according to afterburner, each gpu on the 6990 has 2gb available, and playing tribes ascend, fallout new vegas and skyrim are all drawing 1900MB +

Now these arent really demanding games, but somehow im using up heaps of vram, and the extra 2gb would be handy for futureproofing etc.

What do you guys think, the FTW is $419 and the 4gb is $485. the price difference doesnt really bother me, as the reference 670 is over %500 in australia ATM

Thanks

4Gb's, better to be safe than sorry. 4Gb definately wont be overkill at your resolution or even if you decide to upgrade to even higher resolutions

Do you really have to even ask? 4GB is your clear choice, especially with multi-display setup's.

yeah, sounds like 4gb is the way to go.

anyone know why afterburner is reporting back massive amounts of vram usage?

Saints row the third is apparently using 3900MB with maxes settings and 2x AA

You sure, because this is what MSI afterburner is reporting, not bandwith or speed, but VRAM usage

Wait sorry wrong thing.

It was an issue afterburner has when you have multiple GPUs.
It means you divide VRAM use by the no of GPUs in your case 2.

2GB. If you look at my graphics card reviews, you'll see 2GB's not having any trouble at all in Eyefinity or Surround.

V-Sync can take up a large section of VRAM, as well as MSAA. MSAA is SUPER VRAM hungry. turn off all AA and then check what the usage is at. An alternative you could use for AA would be an FXAA shader hook you could attach on to game.

Ayn Rand is the author for people who want to act like complete douche-bags, but don't have the balls to just admit that they are douche-bags.
"There are two novels that can change a bookish fourteen-year old's life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs."

If it's one (which it's not) I'd say 2GB but since it's two, get 4GB because memory would be a factor with SLI and your resolution
