Again proved what I've been saying on OCN all the long.

On a single 1080p monitor the 580 1.5GB got 64.5 FPS vs 580 3GB that got 65.2FPS is 'miniscule' difference running Crysis, a game that exceeded the 1.5GB VRAM ceiling. Even running out of VRAM didn't effect performance on a single monitor. He even said that could have also been that the core clock on the 3GB card was a bit higher that could have produced that slight 1 FPS gain.

So for those who are spreading false info on OCN constantly on single monitors that 1GB isn't enough, please stop. It's bad advice and pointless money spent. What happened to all those price/performance AMD fans? The 2GB cards aren't a better choice over the 1GB cards for performance on single monitors.

He also confrimed that on multiple monitors VRAM truly effects performance as more memory is needed to store the info it's rendering. More VRAM in this case is better.

My strong suggestion to anyone thinking multiple monitors is 3GB cards. Todays 2GB cards will need to be replaced with 3GB cards for better performance as gaming VRAM grows and spread across three monitors at high resolution. Here is where 3GB is better than 2GB.

Nice find and proof Deadremix. Linus knows his stuff btw people smile.gif I'm going to link this to other posts that need an education but don't believe those who are posting. I guess seeing is believing thumb.gif

For the areas I have in bold, this is what I have to say:

There's more than likely a reason why you'll notice a huge performance difference when comparing the situations, and that's because in the first one (using the two variants to run on a single monitor) the difference in the amount of VRAM being used was miniscule, and therefore the performance difference was 'miniscule'. In the second situation, there was a HUGE difference in the amount of VRAM used, and therefore a huge difference in performance.

My ultimate point being that VRAM does matter, because if you take the first situation, but instead of putting up the 1.5GB variant up against the 3GB one, you replace it with a 1GB version (one doesn't really exist, but that's besides the point here), I'd be willing to bet you will notice a HUGE difference in performance. That's over 500MB of data that just vanished to smoke, and that will certainly have an impact on performance.

Since the OP here is basically deciding on whether he should stay with 1GB of VRAM or more, I would strongly advise for him to at least consider the idea of getting more VRAM, no more than 2GB though, since I'm certain that will suffice.

Also... the game he tested was crysis 2.. which isn't a huge memory hog...

Metro would of been different...

He also said to look at the bigger vram cards if you were considering sli

I'll try compare the GTX560ti 2GB and the 2GB 6950 (maybe the new Sapphire to unlock), and see which would be better. If it's going to exceed 1400mb VRAM it may be worth 2GB. I think I'll go with the 560ti though. With the amount of 3D work and OpenGL rendering it may be worth going for nVidia. The Cuda Cores help a lot with 3D rendering from what I've read. Thanks!

You wont get 60 frames out of a gtx 560ti unless you lower settings.

the 1GB 6950 is better than the 560 ti and is basically the same price. however if you get the 2Gb 6950, you'll have a pretty chance to flash it to a 6970

at 1080p, the core of this card will reach it's limit before the vram will be used even close to 100%.

i game at 2560x1600 and when i had a gtx 560 Ti the core and the vram were just about neck and neck.

the only reason someone running 1080p would need more VRAM is if they plan on upgrading to multiple monitor nvidia surround or plan on buying a second one for SLI in the future.

If your wanting to max out BF3 @ a constant 60 FPS you'll need SLI 580's.

My single 3GB 580 runs everything on Ultra (This is debatable, and the final high res textures aren't till the final game) I would get a steady 45-50 FPS, sometimes 60 outside Metro, and inside it would be around 70ish.

So with that being said, get a 2GB to 3GB card.

EDIT - And the BF3 Beta took 1.7/1.8GB vram MAX from my 580. So I can only imagine what the final game will be like, if not better (I hope), it will take more.

BF3 uses as much VRAM as it can...

it uses 968mbs on my GT 450 at work

and uses 1.45gb on my 2x480s in surround at home.. tongue.gif

it just loves it RAM...

but i think it is more of a cache rather then a actual need...

The 6950 1GB vs the 560ti 1GB or the 6950 2GB vs the 560Ti 2GB run neck and neck with each other on par with benches. They trade blows back and forth with wins and where one wins the other is marginally behind. Niether run away from the other.

Here's another fact.....the 6950 unlocked can over clock slightly higher as it's already being pushed far or the 6950 unable to be unlocked can be heavily over clocked and both performance are the same whether unlocked lightly over clocked or just heavily over clocked without being unlocked. AMD users have confirmed this on the AMD threads over and over again amongst themselves.

The 560Ti is also a very good heavy over clocker that matches either above scenario. Again pulling into on par performance. It's a beast of an over clocker like the 6950.

Both come in 1GB and 2GB flavors.

so in short....

it is a matter of preference...

Nvidia or ATI...

for your use well almost the same...

But remember nvidia have Physx and Cuda...

which alot of new games are starting to use
