Quad GPU's don't scale very well in most games, max is 3 man. I speak from experience, either get 2 7970's or find a way to run 3 GPU's, not 4 though.

On his case, a single 6970 biggrin.gif Should actually reduce stuttering.

@OP: Compare trifire vs quadfire and decide. You can safely skip 7xxx and save money for the next gen. We don't even know how Nvidia will fare against 7xxx series.

I vote 7970's first of all its more efficient, faster and quad crossfireX doesnt perform as well as Crossfire, If its not that much more expensive to go 7970's its a easy choice.

2x 6990s are more powerful than 2x 7970s for Eyefinity user.

some have voltage issues and others don't
some can't get above 1150 stable, others are running at 1300Mhz
some can't run Crossfire correctly, others are running Quad-fire with excellent scaling
some have issues with the drivers and undesirable performance numbers, others are getting near 6990/590 FPS oc'd
so yea...

This, and/or wait to see what nvidia has to offer.

I would get a 6970 and Tri-fire them. 4gpu scaling is not that much better than 3.

Get a HD 6970. For most games that actually work with Quad Fire HD 6990s will be faster. Having 3 x HD 6970s its like having 1 x HD 6970 per 1080p which is very good.

wut? 7970 when OC'ed is not far behind 6990. 2 of them will actually be faster then 2 6990's. And u wouldn't have to deal with heat coming from 4 GPU's, would also have lesser power bill. I see 2x7970 as a win-win option here. Ppl r so unpractical suggesting 2x6990

2 6990's does not make any sense at all when 2 7970's are an option.
