[Soul Bleed]

Currently using the on-board graphics processor on the motherboard.
I am running AMD Athlon 64bit 3500+ Processor
Windows XP Proffessional Service Pack2

Current graphics processor:
PCI ATI RADEON XPRESS 200

I have one slot available for a PCI Xpress Graphics Card.

I will be going with an ATI card, but what will be a good upgrade from what I am using now? thanks for your help...
