SLI Question: 2 Games At Once?

post #1 of 14
Thread Starter 
Heya,

Will SLI help my performance if I had 2 monitors. 1 with a full screen game, and the 2nd with another game in windowed along with my other programs I have going?

Getting tired of alt tabbing and having to minimize one game to go play the other. I switch between them frequently, mainly I socialize in one while I actually play in the other.

SLI 460s might work for this, but you'd likely see a drop in performance for both games, since SLI isn't a 100% performance increase. I think the 460s have 75%+ scaling though. Turning down the game used only for chat to minimalist settings and throwing on Vsync would be a very good idea.

But yes, it could work. A single card powerful card (570,580, 6950, 6970) would also work.

I know generally a single powerful card works better, but in this application would it still apply?

Yes, it would still apply.

Both cards would be running both games, the drivers wouldn't set it so that card 1 runs game 1 and card 2 runs game 2.

if that is the case, i would run the card separately (SLI disabled mode) and connect each monitor to each card.
card 1 will be responsible for game 1 running on monitor 1
card 2 will be responsible for game 2 running on monitor 2

if you set them in SLI, only one monitor will receive full 3D acceleration.
furthermore, VRAM will be copied, so when you alt-tab to the other game, the OS have to switch out the VRAM of one game and put in the VRAM of the other game. that causes hitching lag and high RAM usage.

Ah, you can do that? I wasn't aware that you can hook up the monitors that way or even have the games run like that. I thought it was like how the previous poster said, that the driver couldn't differentiate.

I am not interested in SLI for the performance increase as much as I would just like to be able to run 1 game on 1 monitor, and all my other junk on another while keeping full 3d acceleration on the applications I use.

I'll be playing/socializing between Age of Conan, Second Life, SW: The Old Republic, All Points Bulletin, and possibly Vanguard: Saga of Heroes. So any of those two or three open at any given time along with Photoshop, Dreamweaver, Chrome, WinAMP, Steam, MSN Live Messenger, and Skype.

I'm considering a processor upgrade too

I might have other shooters open too like Killing Floor. Since I play on servers with high waves, there can be a lot of downtime if I die early.

Didn't APB's servers shut down?

Yeesh, doing all that I'd start talking upgrading Processor to a 6-core/i7 and adding more RAM as well as a graphics card update. The catch with Non-SLI setups is that one card ends up completely inactive for your game. Especially in MMOs, VRAM can be filled easily (large numbers of people on screen), so while 2 non-SLI 460s would work, you wouldn't be playing at the high settings that SLI 460s would.

Any chance we could get a budget you'd be working in, see if we can't figure out a plan for you?
