XP drivers for Sonic Vortex & Rage Fury

I have finally given in to friends telling me that I should upgrade to XP from 98SE and now find that both my video card and sound cards cannot find a correct driver. The video card is an ATI rage Fury Max dual processor and the sound card is an Aureal2 or Sonic Vortex2 (depending on if you believe the box/manual or IRQ printout that I keep, not sure what the connection is here).
My system is an ageing Athlon K6/2 450 with 320Mb RAM and a 90Gb HD. 98SE worked OK but I now want to benefit from XP having seen it on my laptop.
I know the processor isn't the fastest but it is within the MS minimum specs.
Can anyone help with drivers or should I just reformat and reinstall 98?
(a new pro & m/b are presently beyond my budget)

 

ps thanks for reading and hopefully responding to this
