I have gotten my new 2.4 GHz Athlon system running RedHat, and even 
gotten the new NVidia graphics card (Asus V9280S Ti4200 based) working 
with the NVidia drivers.  I think it was also running in AGP mode (the 
NVidia /proc entries indicated it was running 8X AGP), but it still 
seemed pretty slow (based on dragging a large window around on the 
screen).  I am running RedHat 8 (X 4.2 and the default Gnome install). 
  I haven't yet tried KDE, but it's installed, so I can try it if necessary.

By "slow", I mean slower than a Win2K Athlon system (1.2 GHz) with an 
NVidia GX2 based VGA card for the same operation (dragging a window, 
with the window contents moving too, not just the window frame) in the 
same operating mode (1280 x 1024 x 24bit).

I'm considering getting different graphics card for the linux system 
(since it looks like getting a 2-user system running with the NVidia 
closed-source driver might be intractable), and putting this card into a 
windows system (for directX game-play), so I'm wondering which cards 
work "best" for linux.

"Best" for me means accelerated 2D performance (ie rapid window drawing 
and moving) at high resolution (true-color, 1280x1024 or 1600x1280), 
rather than 3D performance.  Since I'm thinking of trying to get a 
dual-user system running (involving an unknown amount of patching), I'd 
like a card with good open-source drivers, which should be available in 
both AGP and PCI versions (since it looks like I'm going to need two 
physical cards to do true dual-user...saddly, I don't think I can get a 
dual-head card to talk to two different X servers at once, although I'm 
still investigating).  I do have an older Rage 128 card (PCI), if that's 
a good choice, but I'm not against buying two entirely new cards.

Any suggestions or URL's for good info?

P.S.  Is there an unambiguous way to tell if I'm talking to the card via 
AGP?  While I'm very familiar with low-level linux config for most 
things (SCSI, networking, RAID, etc), this is my first big forray into 
the linux desktop world, so I'm unfamililar with the whole video driver 
mess.
