Hmmm, isn't there an AGP-PCIe bridge being sold? With that you should be
able to install your AGP card onto a PCIe motherboard. This may be an
urban-legend though, since I, myself, did not double check it. By the way, I
had the same problem, but the other way: I wanted a new GPU, but I was happy
with my system. So, for me, it was a new system with PCIe or not for a new
graphics card. I ended up buying the AGP version and keeping my system.
By the way, you sould be able to sell the old card on eBay, still for a
decent amount of money, which would ease the pain of $500 for the new card,
if you decide to go that way.
Good luck.

I've never had a problem running my apps and games with the 6800GT. I'm
planning on upgrading my system and I'm trying to decide whether I should
keep my BFG 6800GT OC 256mb AGP8X card or jump to the 7800GT. If I go
with the 7800, I buy a PCI-E mobo. If I keep my 6800GT, I'd buy an AGP
board. I know it's "old" techonology, but it would allow me to continue to
use my 6800GT for one more go 'round.

Obviously, there is a performance increase but is it worth shelling out
$500 to go from the 6800GT AGP8X to the 7800GT PCI-E?
