Hello there,

I would like to build a new computer, its been a long time since I built a computer by myself (4-5 years ago). For my daily work I need four screens, this means I need two video cards with two DVI outputs (because I already have those four screens with DVI Input).

I'd like to use this mainboard:
ASRock 970 Extreme

and two of those video cards:
Sapphire HD5450
hardware support DB for video cards (last entry)

Do you have experience with this video card? Or some knowledge of using two video cards in one computer running ubuntu.

I looking forward to your replies.

Thanks and best regards
