A 1GB card is fine for 1080p.

Think about it, 2GB-3GB cards are fine for triple monitor gaming, nobody really reports of them being VRAM bottlenecked. For a single monitor you don't have to worry about VRAM, just what card you're getting, and how fast it is. A faster card is going to have more VRAM anyway (usually).

Pretty much this. I monitored my Vram use on a 570 at 1200p and it was usualy around 1100-1200MB in the most demanding games, but I never once saw a performance hit for it. Even with 3x570's pushing it there was no Vram issue even though the GPU power was there to possibly cause one. I wouldn't worry about it a whole lot, fact is people have been using bigger than 1080p screens for years, and its only in the last year or so that 1GB+ cards really became common.

bf3 eats over 2gb on my 3gb 580s, but that is 1600p with AA. 1.25 should be fine at 1080p for a while. some people will tell you that more than 1.25gb can be used @ 1080p, and they're right, but you won't notice much of a performance hit tho

Here's some food for thought.

On multiple monitors VRAM is king. More VRAM helps because memory is being spread across three screens to render graphics.

On a single 1920x1200 resolution monitor performance is not as VRAM dependant or has the ability to utilize it as much or need to. Until games exceed 1.5GB you won't feel but the slightest difference between 1GB vs 2GB.

It's a huge debate and has a lot of varying opinons. Finding the line where you run out of memory on single monitor is speculative still at this point. Not enough data to be accurate.

At 1080p you will be able to max battlefield 3 all the way out and never drop below 30fps and usually be over 40fps. At least that's what I can do if I just use one card.

Not sure what 3.0GB/1.5GB/2.0GB VRAM chart on three monitors with 5760x1200 resolution has to do with the OP's question using a 1920x1200 resolution single monitor "So can some explain the 1gb vs 2gb VRAM Debate?" says anything. tongue.gif They are entirely two different results. tongue.gif His question was obviously on single monitor because who uses 1GB on a multiple monitor?

Yup, thats the extreme end of the scale but remember when they dial down the AA to 4x the vanilla 580 does fine. So you can say that 5760x1600 it the practical limit for 1.5GB.

Tom's hardware posted an article recently comparing 2gb and 1gb 6950s, to see if the extra ram was worth the money, and there was only one game they tested where it made a difference, and that was Metro 2033 @ 2560x1600 WITH 4x AA, without the AA it was irrelevant
