Having an AGP system isn't that great at all especially when trying to upgrade. But finally I've upgraded from a 5200FX to a 6800XT ($40). I could have gone for a 7600\7900 but my budget is extremely tight ($50 or less) and this was all I could get.
In terms of mapping, I can get back to it now as it's the holidays and my second hard drive works again as it has all my mapping stuff (IDE cable wasn't in right... /facepalm).
This has nothing to do with you but when you mentioned agp it reminded me of that time I was an irrrrrdiot... still using the computer but I went out and bought a pci x16 card :]
YAY mapping during the holidays!
And yeah mapping on the holidays... plenty of time~
I've got the most powerful card This computer can have, so in a bit I'll have to upgrade to PCI-E

6800GT AGP
6800GT PCI-E version
Notice how the connectors from the PCI-E version differ from the AGP?
I am currently in this situation.
