QuadSLi 590s is heavily limited by that VRAM and the underclocked 580 gpu in each. I stand by the recommendation of 2 x 3GB MSI Lightning Extremes.
I hope you realise that 3gb gtx 580 sli, will have the same amount of vram as a single 3gb gtx 590.

By doubling your cards you are not doubling your vram.

Also, 3gb of ram is much overkill for a 1080p setup - 1.5gb will do it easily - however, it can pay to be future proof. But if your investing in a 120hz monitor (which you will love by the way) and 580 sli, I imagine you will be planning on using this setup for several years, if I were you I would just stick with 1.5gb to save money. Honestly and sincerely, 1.5gb is all you will ever need for rendering 1920x1080 frames. I have yet to need any more vram with my 1.25gb 570s. The 3gb cards were made for eyefinity in mind, or 1600p setups which have more then double the pixels of a standard 1080p monitor. Also, theres no point using 3 monitors when you have a 120hz monitor, because you can not run the middle one on 120hz unless you bought two more 120hz monitors, then you would be trying to run 5760x1080 resolution which is 3x the size of standard 1080p, at 120fps, which would just be insane.

But one thing is for sure - you cannot go wrong with 580 sli, and I would recommend the lightning ones. 580 sli and 120hz monitor, would be so much win. Do it!!!

No. A 590 has 3GB of VRAM total that is SPLIT between two underclocked 580 gpus. Each "core" has only 1.5GB of VRAM. With a 3GB 580, the graphics card as a whole has 3GB of VRAM to use. So SLi 3GB 580s has 3GB for each GPU to use not split between the two.

Hates a strong word. That was wrong. I just think its silly.

No it won't. You're off your rocker if you think 2 Keplers will cost $1200, because that is what 2 3GB 580s will cost him. Hell, 1 3GB 580 costs $600, and a standard 580 costs ~$450. The best single GPU Kepler can't cost more than maybe $500 at max. The 580 was once at about $500, and that was the best Nvidia had to offer. They would not exceed their max of the last generation of GPUs when AMD is on the upswing, and they cannot afford to screw up.

The best single graphics card is a 6990, the best (comparative) dual setup, is 2 X 580s

get two 4G ATI 6990's for $1450, that would be faster then the two 3G GTX 580 & the 590. and it will give you 2-3 years of maxing out any game .

Perhaps you aren't meaning to say ... what it appears you are saying.

But what you seem to be saying ... is incorrect.

Not the last part, just the first part

SLI GTX580 3GB (iow 2 x 3GB total) cards, does, in fact, have double the vram of a capacity of a GTX590 (iow 2 x 1.5GB total). The former has a 3GB capacity, the latter has 1.5GB capacity.

He doesn't need the 4gb 6990, 1.5gb is enough for him @ 1080p.

two 1.5gb GTX 580 lightnings will survive max for a year or so because no games in the future (yet) are going to be as demanding and good looking as bf3 (atm)

2 580 lightnings are plenty @ only 1080p.

Which two 580's in SLI would be best for low noise though ?

You think 1x HD 6990 'll perform better than 2x NGTX580 Lighting Extreme 3GB GDDR5?
And much people say 2 opinions 1 to buy 2x gtx 580 ex ligh ,other opinion don't buy ,so what should i do?Maybe wait for 600series?Or just buy 1 or 2x?

And what 2x msi gtx580 lightning xtreme gives more than 1x?I can spend not more than 1500$ on GPU.But that 'll be investing in future.
