"Cheap" > is word I'm looking for :-) You'll need to use the binary nvidia drivers, the open source nv=20 driver doesn't support dual-head at all. So you run in to a couple=20 of gotchas there. The first being that the nvidia drivers are i386=20 only, they aren't available for AMD64, and the second is that=20 twinview has a sort of odd behavior when you use different=20 resolutions on each monitor. It's hard to describe but the driver=20 basically pretends that the resolutions are the same and then only=20 draws what can be displayed of the smaller one, so there's desktop=20 outside of the monitor that you can drag windows in to but obviously=20 can't see. With regards to cards I've used the recent nvidia drivers and=20 dual-head with everything from an fx5500 PCI card to 6200LE to 6600GT=20 to 7200 cards. I've used the legacy drivers with various 4x00ti=20 cards. Here are links to cards I've personally used with dual head in the sub=20 $50 range USD. pci-e http://www.newegg.com/Product/Product.aspx?Item=3DN82E16814121080 agp http://www.newegg.com/Product/Product.aspx?Item=3DN82E16814127290 =2D-=20 Thanks, Josh Paetzel --nextPart1641881.D1l6Yeyt4U Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQBGnLiDJvkB8SevrssRAorlAJsF+ZClJenW+DLMtA/IZNwlEIeiSQCgioCj yT+lPSPe6YzUAw0rUOGhVcg= =7hqP -----END PGP SIGNATURE----- --nextPart1641881.D1l6Yeyt4U--
