Probably. I wouldn't expect PWgui to be really graphics-intensive,  
but for sure you won't be able to run (for example) XCrysDen at  
decent speed without 3D graphical acceleration.

I'm afraid there's no easy answer. What I can tell you is:

If your card is supported by the free "ati" driver (I don't know),  
you should be able to turn direct rendering on by setting your X  
configuration correctly. How to do that depends on which distribution  
of Linux you are running. In case it's Debian, I'm attaching my X  
config file; that may or may not work for you. (My card is a Radeon  
Mobility 7500.) You may also gather some information by running "man  
radeon".

If your card isn't supported, you'll have to install the proprietary  
(but free of charge) "fglrx" driver released by ATI. Again, if you're  
running Debian, you can find instructions here:
http://xoomer.virgilio.it/flavio.stanchina/debian/fglrx-installer.html

To find whether your card is supported, I'd suggest you try Knoppix  
(in case you don't know, it's a Linux live-cd, that is, put the  
Knoppix disc into the cd drive, reboot, and it'll load Linux from the  
cd without touching your hard disks. When finished, remove the cd,  
reboot and you'll be back to your existing operating system). It is  
generally believed to have the best hardware configuration support,  
so if it can't enable direct rendering with your card, no other Linux  
probably can (although I've seen one counterexample). If it can, you  
can probably copy its X configuration to your system.

If this isn't enough to solve your problem, I'd recommend that you  
ask for help on the user support mailing list for your Linux  
distribution (for Debian, debian-user at lists.debian.org).
