A bit confused...

post #1 of 11
Thread Starter 
I didn't know exactly how to search for this, but here is my question. So from reading on OCN I have come across some conclusions:

A single GPU card is better than a dual GPU card setup (ie: 6990, 590 gtx)

1 GB vram for 1980x1080 (or1200?)

2 GB Vram for 2560x1200

Sooo... lets say I want to do a dual 2560x1200 ips setup. And lets say that I have I have 2x 2 GB Vram cards (5870 in my case). Is it possible to run two monitors on a seperate card and run windows in extended mode? (assuming what I have said above is true)

You mean running each monitor on one 5870 2GB? And not doing a crossfire setup? Yes.

Yep, each monitor running on a separate card. But will it work in extended mode?

Edit: And is this better than running in crossfire? Meaning that one GPU is only outputting half of the image on each card?

Yep.

And it depends what you're using your computer for. For everyday work (web browsing, etc) it doesn't matter. For gaming on one or both screens, crossfire is better.

Why would crossfire make it better? What would be the most efficient way to use 2 2560x1200 monitors? Can I crossfire and still keep the monitors on a separate card doing the extended mode?

for the 2560x1200 resolution it is better with 2GB of vram...same for gaming...crossfire is better than running each screen on a separate card...

I do understand that... so are you saying that I could run 2 2560x1200 monitors on the same card in crossfire?

It basically helps the cards work together, minimizing microstutter, etc.

okay thanks. But is running two monitors on two separate cards in crossfire mode possible? I never tried it before.
