Is 2gb Vram really necessary for 2048x1152?

post #1 of 27
Thread Starter 
My monitor is one of those rare samsung syncmaster bwx with a wierd ass res. I was just wondering, if I wanted to max out my games with a decent fps count, would I need a card with a Vram more than 1? I'm not planning to do a double or triple monitor setup ever. So, basically is it necessary? Or would it be highly recommended that I get it?

It depends on the game and the settings. You can max 1GB of VRAM @ 1680x1050 depending on the title and the settings.

Alright lets make it this scenario since im crossfiring/sli'ing my cards anyway. I want to run Metro 2033 maxed out with either 2 560's 1gb or 2 6950's 2gb. For the sake of argument lets just say the 560's are at exactly the same speed as the 6950's ( FPS wise). Would I really need 4gb of vram in that case or would 2 perform just as equally.

Vram does not add up. If you got 2 gpu's with 2gb ram in SLI you end up with 2gb of total vram.

Then why does everyone tell me to get a 2 6950's for the extra vram over 2 560s if they'd both be 2 gb anyway?

The ram doesn't add up. SLI 560s would be 1gb and Xfire 6950s would be 2gb. Because 560s are 1gb per card and most 6950s are 2gb per card.

with the 6950's you would end up with 2GB usable VRAM, with the 2 560's you would end up with 1GB usable VRAM. With AA I doubt 1GB will be enough for that res

You don't get the Vram of the second card added, but if you have two 6950 that are 2gb each, you'll have 2gb total. If you have two 1.5gb cards, you'll have 1.5gb total.

Anyways, I haven't ran out of Vram yet at my larger 2560x1600 resolution, with my 1GB of VRAM, so you should be fine.

That's not a weird res, that's the standard max res for most 21" CRTs (but it's 2048x1156).
