Graphics Card Question,

Hi,I have aparently been wrong in what I was using,or was I?I was told that if I wanted to run a duel monitor set-up then I should but a secondary GF2 PCI card to use my second monitor in FS2002,for example, I use the main monitor a 22"er for the forward/main cockpit view on a GF4Ti4600, I also use a GF2 for the second monitor so I can see FS Nav on the other 21"er whilst flying without having to keep pressing F9 etc, but I thought that if I just used the GF4 Ti4600 and plugged both monitors into it then I would get performance loss and stutters in FS, now I have just been informed that I wouldent get this at all,and that in fact it would probably make it all run better as I am not drainint PC resourses from the add-on PCI card from the system resourses, confused, well not as much as I am I can bet,if you have any advise here please reply to this post as I would welcome it,I am going to up-grade in a few weeks to a Herculese 9800Pro,with a AMD XP3000 CPU, I allready have 1024MB of RAM,Thank you,Steve
