2-Way SLI: 3 Displays possible?

post #1 of 33
Thread Starter 
Hey guys. Simple question; I just wanted to know: Can 3 displays optimally run on a 2-way SLI (specifically on 2 ASUS GTX 460s overclocked)?

And if so, how will 3 Samsung 23" 1920x1080 Displays perform on them?

I don't have this system setup yet, but my preliminary specs are:
Intel 2500k
ASUS P8P67 PRO
4GB G.Skill 1333mhz

and of course the 3 Samsungs as displays

What are your thoughts, guys?

3x 1080p on just two 460s might be a little bit too much when gaming, you might have to live without any AA

Thank you for your reply. What should I look at for 2-Way SLI? How would 480s fare?

Possible and it will run in SLI only if you enable surround.
But note that if those are 1GB version, they will be hard pressed and will not give the best results for such large resolution. Especially with any type of AA.

don't buy a 480, buy a 570 instead; they perform much better for much less power consumption

And I think 570 SLI would be pretty okay for 3x 1080, but don't expect any to run heavy games on 8x AA

GTX460 SLI is probably an entry-level graphics subsystem to do 3-monitor setup. It is definitely a good solid first step to enter the world of Surround. And, I suggest getting 2GB versions of the GTX460.

Below is the conclusion of a good indepth review of GTX460 SLI for Surround:
Quote:
For those on a budget, or not wishing to worry about the power draw or heat output of a full-fat GF100 SLI setup, but still wanting to enter Surround gaming, the 2GB GTX460 presents an unrivalled opportunity to do so. Given the little extra cost of a 2GB card over a 1GB card, there is no reason now they are available to go with 1GB cards and risk a ‘settings lottery’ of whether a particular detail setting will push the game into single-fps territory.

Obviously, for those running single screen systems, a 2GB card is just overkill. But as already said, for those wanting Surround on a “budget”… a pair of 2GB GTX460’s for three cheap 1920x1080 or 1920x1200 screens can’t go wrong.

Yes, its possible. It would be better if you can get a card with higher vram, you can get the 2gb version of GTX460.

570s v 480s, I would suggest the 480s.

Yes they are hotter and take a bit more power, but they have higher vram, and much less risk to blow a VRM because of heat.
And they are cheaper atm.

I wrote that review. I also posted it here, but I'm not on much at the minute because I'm too busy.

...

Three displays will run on a GTX460SLI setup, yes - in fact, SLI is required for nVidia Surround, while you can get away with one card with AMD's EyeFinity.

I really wouldn't recommend trying 1080p Surround on 1GB cards. It is possible, but you run into some serious VRAM bottlenecks that just kill performance completely. Remember that with 1080p Surround, you're asking 1GB of VRAM to cope with rendering 7 million pixels. No single monitor can give a GPU the workout that Surround can. If you were thinking of 1680x1050 or lower, it would cope better.

That said, if you've already got the cards, try it - it's not a bad experience, you just need to spend a lot of time tweaking settings so that you don't end up with slideshow framerates. MSI Afterburner and a G15 help too, so you can monitor in realtime the VRAM utilisation.

What the hell are you on about?



Oh yeah 1% is a huge difference. And the GTX480 is like £90 cheaper.
