Decent Graphics card / 64 bit system / imaging

[Labitt, Bruce]

Thanks Arc.  Unfortunately I only have 1 PCIe 16x v1.? slot.  How are
the cards below for 2D?  They certainly seem cheap enough... $49 is not
what I'd call a lot of money.

	So Arc, what video card (ATI or other) would you recommend for
3D 64 bit linux?  I'm attempting to use vtk, are there better tools
available for plotting/rendering/visualization?  I'm trying to visualize
a 1K x 1K 3D plot.

I'm guessing around 1M quads with realtime rendering, so you'd need
around 50M polygons/second for 30fps (considering the software likely
isn't completely optimized)

No problem.  Even the low end PCI 16x Radeons are going to handle 400M
polygons/second, more than sufficient.  Even the "puny" Radeon 9250 in
this system can clock over 150M/second.  This one is considered
mid-range and is fully supported:

2 DVI ports, PCIe 16x, and more than enough rendering speed.

I'm slightly concerned over how much trouble a dual-screen card will
give you in X configuration vs two separate cards, and since it's less
common you may run into bugs.  If you have two PCIe 16x slots it'd be
better to go with two of these instead which together add up to the same
cost and boast almost double the speed:

Both cards are supported in current stock Linux+Xorg without any
"special drivers" needed.  YMMV depending on how up to date your
distro's kernel and Xserver packages are, but that's the case with any
card.
