video Card to support 4 monitors?

[Marc Lawrence <mhl7@xxxxxxxxx>]

Hi All,

I am looking to upgrade my computer system and would
like the ability to support 4 monitors.  I ran across
this article
http://www.esignal.com/exchange/v18_09/your_trading_office.asp
 that talks about the Appian X -  it also talks about
how you need a liquid cooling system installed for
this to run properly.  

Does anyone have recommendations for video cards?  are
there any good alternatives without installing a
liquid cooling system?  If you do need one does anyone
have any suggestions here?   Thanks in advance-  Marc
