Would a single MSI N580GTX Lightning 3GB be smoother with less microstutter than SLI?

post #1 of 20
Thread Starter 
As far as compatibility problems, performance problems, and microstutter, would a single MSI N580GTX Lightning 3GB be better than SLI options (dual or tri-sli)? Would a SLI setup really give a noticeable performance increase, or would the single GPU be smoother anyways because of much less chance of microstutter?

BTW, I am talking about gaming at 1920 x 1200 resolution.

Any responses will be appreciated.

Thanks.

Smoother because of such a low res.

For a single-monitor setup @ 1920 x 1200, 3GB is unnecessary overkill. The 1.5GB of most 580s is quite sufficient.

What CPU do you have right now, and what is your current video card?

No, GTX 560 Tis in SLi would kill the 580 3GB at 1920x1200 despite having only 1GB of VRAM.

So far I've yet to experience any of the microstuttering problem people speak of (usually people who say it's a problem only have a single GPU).

The 580 3GB is such a terrible product for the price considering the only reason you would need that much VRAM is for 2560x1600 or higher. At those resolutions the HD 6970s in CFX equal the performance of 580 3GB in SLi in performance but cost $400-500 less.

I am planning on building a gaming rig and I have a $5500 budget. Therefore, I want what will give me the best performance. I want excessive power on my system so that I can turn up all options on games for the next year or more at least, and be able to play games with good visual quality for 3 years. That's why I want an excessively powerful system.

However, I don't want SLI if it's riddled with problems and gives less smooth gameplay than a single GPU. If SLI is problematic, I would rather just get the absolute best single GPU option available, and maybe upgrade it in 1 1/2 to 2 years.

What's your recommendation?

Thanks.

I just got my MSI LE 3gb in sli last night, i am planning to do surround, but i do notice even with my same res as the OP i am able to crank everything to max with a much much better framrate in games like Metro and BFBC2, im talking everything on ultra high AA to max and texture filtering to max etc.

Although my single 1.5gb 580 was able to handle similar high setting, the ultra high stuff would usually bog down my framerates to a point i didnt like. Although at this point its not the vram helping me get better FPS its the cards in SLI.

OP i would reccomend only 2 580s in SLI, or even 560tis, or 570s, all scale well and will give you better performance than a single. If you are wanting to crank ALL that pretty eye candy in the titles you play, the difference is very noticeable in metro and bfbc2, although stick with 1.5gb cards, becuase as everyone has said 3gb at this res is not just overkill its a waste.

The only reason to spend that much money on a gaming system is for a 30" 2560x1600 monitor or 5760x1080 over 3 monitors.

For those resolutions, you pretty have to use two GPUs if you want decent frame rates. I know at least for nvidia the SLi experience is generally very smooth.

Not like a single 580 can possibly power through 3GB worth of VRAM.

I may be biased, but I recommend using the i5-2500K overclocked to at least 4.7 to 4.8GHz with the GTX 580. To my surprise, it's extremely powerful. You'll be able to upgrade to Ivy Bridge because it's socket 1155, and you'll be able to replace the 580 with the next option in its class (perhaps the GTX 680?).

3GB of memory is really only going to be useful with either an enormous resolution, or multiple monitors (which results in a big resolution).

This, although even with a sb OCed even to 5ghz some of the high end graphics options will still give you frief fps wise, with that being said though the framerates arent horrendous, lowest i saw on my single 580 was around 25 in metro on some crazy intense parts. The slime room comes to mind, that part was just terror on my 580!

I couldn't max out metro on three screens using three 6950s unlocked. I have three 23s so I'm sure three 580s w/ 3gb shouldn't have any trouble maxing out Metro2033 @ 3240x1920/5760x1080.
