Hello,

I wanted to build a powerful yet not so expensive Eyefinity setup. These are the components that i have ordered:

1x Asus Radeon 6950 2GB (Direct Cu II model)
3x BenQ G2420HDBL Screens
1x Sapphire 44000-02-40R Active DP - DVI Adapter

(Other components: OCZ ModXStream 700W, Intel 2500k platform)

Two screens will be connected via DVI and the third will be connected to the adapter.

What you guys think about this setup? Will it cause problems? Did i make a good choice regarding the adaptor?

Also, i read on certain forums that its better to connect all screens through DP adapters. Is that true? Will 2x DVI and 1x DP will be somewhat incompatible?

Thx,
redrat.

Don't be too surprised if you have any power related issues ..

Your PSU outputs 23A ( 25A Peak ) @ 12v on both 12v rails ..

Your HD6950 draws about 17A under load ..

.. that leaves just 6A nominal to power everything else which is hooked up to the 12v rail powering the peripherals if one 12v rail is dedicated for the CPU / EPS12v only.

The adapter is fine .. x2 DVI & x1 DisplayPort configuration shouldn't be an issue.

Yep I run two DVI and 1 display port. No issues. 

Although 1 6950..... Games like Modern warfare series will run great.

Games like BF3 your 1 video card will struggle. I know my 5870's do... :-)

Hello again!

Thx for the replies.

My components arrived just the other day. Everything is set up, works well i guess, but i do get some screen tearing. Going to try to find a fix for this issue, maybe some different driver version.

About the power issue that Gr33nGecko spoke about, i did not encounter anything, and i did a system stress test for about 1 hour. (My videocard did not pass 74 degrees with fans manually set to 50%

I was able to to run Crysis and Crysis Warhead and max details with 4x AA at decent FPS, Crysis 2 however with DX11 and High Texture Pack didnt run as smooth, had to lower all details.

I will do some more testing these days, will come back with more details

redrat.
