Crossfire & eyefinity

[nmiro1]

i am getting 2 PowerColor Radeon HD6870 1GB and was wondering can i run 8 monitor eyefinity?

It seems 5 and 6 are the limits.

Here is a active eyefinity display configuration tool applet.

You can only use six (2 each with DP, and 2 Legacy), with Crossfire you can only use the outputs of one card.

But you can RUN 12 monitors however.

I dont see the point beyond 3, but thats just me. I prefer 1 big monitor over 3 small ones anyway. Bezel is a little annoying. But to my knowledge, single card has a max of 6.

theres one difference between using one big monitor and 3 smaller ones tho. with one monitor u will still have 1920x1080 resolution, with 3 monitors u will have 5760x1080.

The bezels is actually not anoying, a game that fully supports eyefinity you will actually see the same thing on ur single monitor as we do in our middle monitor. This means that we actually have 2 EXTRA monitors of view that u will never get and behind the bezels is just things that none of us can see.

Actually you could have 2560x1600, and 30". Probably costs the same as 3 decent monitors for eyefinity.

Yea that is true that u can buy a good monitor with that high resolution but its not that common yet.

ah well, we all think different But to pick between Eyefinity with 22-24" and a 30" with that resolution would be a hard choice for me tbh Both of them have their advantages and downsides.

While the eyefinity setup would have more pixels, i wonder which one would get the better FPS.

The 30" monitor for sure. But that shouldnt be an issue if u just have a good enough computer to run eyefinity and ur not afraid to let go of 8xMSAA and go with 2-4x instead.

But as u said.
Eyefinity will have more pixels. but you will also get a stretched view in some games and u might have to go down to just using 1 monitor.
The 30" will have morepixels from top to bottom and will work good in all games without any stretch, but it will miss alot of the extra view to the sides that eyefinity gives.

The greater pixel count will lead to lesser fps. So the 3 monitors with 6,220,800 pixels vs. the 1 monitor with 4,096,000, the extra 2 Mil pixels (50% more) will run slower.

That's why I'm a fan of the three 5:4 monitors yielding 3.9M pixels (same as the 30" monitor) but gives a wider viewport and has move utility (3 separate screens). You can drive it with a single 5850 even. (Currently running 5850s in XFire with it). However, the 16:9 movies in games bleed into the adjacent screens (lazy developers...) so until this is handled correctly, it's definitely a minus to this setup.

Followup: Just out of curiosity I looked into what a 2560 x 1600 (16:10) monitor would cost...and... _holy crap_. Seems minimum price is $1,200. I'll take bezels and almost equivalent pixel count from my $200 3x5:4 setup any day over spending another grand. Whoof.

No, they can be around $950-1000. The IPS ones are more expensive.
