Recently ordered my build, it's on the way

sapphire 7970 ghz edition 6gb vapor-x edition
intel 3750k processor
850w psu

Anyway, was thinking about running an eyefinity setup, and in order to handle gaming on this system I was told I'd probably need to run dual gpu's.

Is there a way to set up a 3 monitor system with a crossfire setup WHILE TAKING ADVANTAGE OF THE BOOST FROM THE SECOND GPU?

I am reading alot of stuff that says only one card can be used with an eyefinity setup. Is this simply old advice, thats simply outdated? Or is it still not possible to take advantage of the second gpu when running this kind of setup

thanks in advance :]

That advice has never, and I mean ever, been correct. Crossfire and eyefinity have always worked together. And are designed to.

In eyefinity all monitors must be hooked to the same card, but that has nothing to do with crossfire, and crossfire will work fine. The same as it would with one monitor (which is obviously also only hooked up to one of the two cards)
well for starters you chose the wrong brand for a dual gpu setup, with recent revelations in testing and FCAT dual AMD gpu;s don't have all that much of an improvement over a single card in perceptible performance increase. although amd are working on that, expect a few months before they release a driver that shows real improvement on frame pacing in multi card configs. Nvidia has been working on evenly spacing frames and smooth gameplay in multi card setups for much longer than just trying to achieve high "benchmark fps" like amd does

Hi Yes you can crossfire with eyefinity mode ... I know this as im doing it ..

1 When setting up eyefinity you connect the monitors to the top gpu when in crossfire mode how will depend on the montors you have and the connections on your gpu.

2 There are 2 types of eyefinity cards std eyefinity and Flex

your card has the same connections as my Sapphire cards and this is how my system is set up with the 3 Asus screens I have:-

Monitor HDMI to DVI cable >> DVI port - 7970 DVI Port

Monitor HDMI to DVI cable >> DVI port - 7970 DVI Port

Monitor HDMI to DVI cable >> Active Display port Adaptor - to 7970 display port

I am aware they have issues at the moment, but i consider it a longterm investment and I am more than happy to wait for the fix.

Thanks for your advice guys. Have really put my mind to rest.

I think, when i can afford it in a few weeks or months time I will get another identical gpu. If I'm not mistaken, two of these cards (which are designed for multi monitor play) will be quite the weapon :))
