Hey guys, I am thinking its about time to upgrade my old Crossfire 4870 512MB's, and with my birthday on Friday thought why not treat myself :)

Now I happen to have two 17" NEC monitors with native resolutions of 1280 x 1024 sat at home, so figured why not eyefinity them up with my 22" widescreen.

So the question is, will a 6870 manage this, or would I be better suited going for a 5870? I don't want to spend any more than £300 on the card, so two x 6870's is out.

Suggestions please!
 
I just set my eyefinity up last week, one thing I am not sure on is if you can use screens of different resolutions, for example you would need a widescreen with a verticle resolution of 1024 which would mean running a weird (non native) res on your main monitor.

Also with mismatched monitors you will not be able to use bezel adjustment. I would be interested in seeing if anybody has set up eyefinity using two square monitors as the side ones.

On my rig I run a res of 5760x1080 and to be honest I have to turn down aa and or af but other than that most things run just fine on my 5850 which is about or just under 6870 levels of performance.
 
Regarding the resolution issue.

It will work if they are different resolutions, but it will turn them all into the lowest of the available resolutions. So you're 22 monitor will be given the same resolution as your other 2 and it will work.

And yes the card would handle that resolution no problem.

My 5850 handles 1680 x 1080 on 3 screens just fine. Ends up with a res of 5760 x 1080 i think and havn't noticed any slowdown. But the last game i tried it with was MW2
 
Excellent, 6870 it is then. (Saves me that additional £80!)

Now my other question, could anyone suggest some good DP - VGA adapters? I don't see any offered on OCUK.

Cheers for that, it clears that up nicely.

As for the adapter, Im using a dp-dvi sapphire jobbie but If you are going to vga then I hear that pretty much any adapter works.
 
I can confirm that you don't actually need an active displayport adaptor to use 3 monitors. I paid for a none active one when there was still confusion as to what would work, and it worked fine. I remember having a few issues setting it up, but it does work. Sometimes though with the none active adaptor it will bring up an error that turns one of the monitors off. To fix that though you just need to unplug and replug the adaptor back in. Never happened during play, just sometimes whilst changing from different applications, e.g game to the desktop.

That can be annoying don't get me wrong, but then i only paid £10 for my adaptor and the official active ones are like £60 if i remember?
 
Bought an official Sapphire active dp adapter for £15.99 from a competitor, the same as this one. haven't had any problems with screens turning off and what not so this could be worth a look.
 
Maybe 2x 6850, there are retailers who do it for £150 each. I would personally wait until the rest of the 6XXX cards come out, hopefully the prices will drop.
 
@Anominity
I run three screens - 2 x 19" CRTs at 1280x1024, 1 x 22" LCD at 1280x1024 (native res of 1680x1050) off an analog Matrox triplehead adapter. One thing is the central screen is stretched horizontally due to the different aspec ratio, which is slightly noticable but does not stop me playing BF:BC2 and Arma2. I plan to move to Eyefinity in the near future, short term I am considering getting a 19" central LCD to match the aspect ratio.
