Thanks a lot! I'm using an HP 6671. Some dudes on another forum warned me it doesn't have a slot for pci-express cards, but I've marked these two agp cards:
Both are decently priced and support TFU.
One Amazon review said XFX's technical support is lame. I suppose I go directly to ATI if I need techn support or another card as per the warranties? I'm confused.
TFU doesn't say anything about supporting cards in the radeon 5000 series. Help?
