6970 eyefinity

[Patriot]

I have mixed feelings on the 6970 rather aggravated about the one single and one dual link dvi....


Ok... I have gone through alot of hardware in my setup... dual 5870s a 5970 and back to a single 5870...
I have three Samsung 2343Bwx-1 monitors... they run at 2048x1152 a piece ... 2 off the 2 dual link dvi plugs and the 3rd off an active display port adapter...

2 questions...
1 how is the hdmi configured in the new card... does it get its own link (can I run dual link dvi off an adapter or does it share signal with the dual link dvi)

and 2 will my accell active display port adapter work with the do1.2 ports on the card?

there are not many people on OCW running eyefinity so I came here...

Good questions

I am considering a pair or 6950s if I go Xfire and I too would like to know if I can use the 2 DVI ports and the HDMI port or if I have to find some sort of mini DP to DP adapter (which adds to the cost though, admittedly, not too much)

It looks like you'll need to use the mini-DP port connector for two of the monitors according to the review. HDMI is single link only. Dual link signaling can't be done over HDMI as far as I know. That leaves you with the mini-DP connectors which means two active display port to DVI adapters unless your display has display port connectors natively. That's a big step backwards if you ask me. Though admittedly that's a small problem and only a problem for people running displays which exceed resolutions of 1920x1200 which seems to be increasingly rare these days. Most monitors regardless of size shoot for 1920x1080i. Most people are hung up on "1080P" and don't realize that 16:9 sucks and 16:10 is where it's at.

Unless I misunderstood the review somewhere.

yeah thats pretty much the conclusion I have come to...sigh

so $380 + $60 adapter... lol when I got my first active adapter it cost $99

of note... for those at or under 1080p... they have $8 dp>dvi adapters for that...

I will deff wait for the eyefinity reviews to see if its worth upgrading from my current setup.

from toms hardware, it is the results of the highest resolution test they did.

It appears that 2 6850's is better then a single 6970 (they cost the same +/- 5 $).

I find this supriseing give 1 vs 2 gig of ram (why you use 2 cards, they mirror ram right, .. it doesn't combine?)

Depends on t he resolution.. at 1080p you're not going to hit the 1GB VRAM ceiling.
