That's what I'm using. They are a great deal at under $180 for the 64MB version. I believe all the GF 4 Ti series support nView (dual-head) for two monitors as well. Most also have TV out.
My only complaint would be the very large amount of power they consume and that their 2d image quality is not quite as good as some other cards out there. Their 3d performance is great though.
Edit: What are your system specs Staga?
