I mentioned the following radeon graphics adapter:
http://www.gigabyte.com/products/product-page.aspx?pid=4278
So definitely it is capable of driving for monitors. The question is if 
it is possible to configure X server in such a way that all 4 monitors 
connected to this particular adapter are in one logical DISPLAY.
At the moment I use two dual head ATI FirePro 2270 graphics cards. As a 
consequence I have two logical (dual-monitors) DISPLAYS and I'm not able 
to span a single window across more than 2 monitors.
