I'm sorry to say this has pretty much been the best thread on video cards so far.
We really need a sticky thread to summarize things.
1-Requirements
2-How to test your system
3-How to pick a new card
4-PCI vs AGP, resolution and other hw issues
5-Known Good and Bad Cards
The civ4 website is completely void of technical details. We really need a beta tester to tell us about video options or even testing on older cards.
I would be willing to help with that or even write it... however, it's really difficult to give exact specs that you should have... I can answer a few right off the bat.
3. The card should have 128 or 256 ram, that is not shared with the ram at all. Good cards would include Geforce 6200, 6600, 6800, 7800, ATi x800, x850.
4. PCI = Old standard, highly inefficent for today's graphics, if you are forced into using PCI you not only will be limited by the slot but by your card selection, as there basically no premier cards for the PCI slot.
AGP = Old but still around. You'll be able to find good cards for this slot type, and since AGP slots tend to be universal compatibility shouldn't be a big issue when picking a AGP card.
PCI-E= PCI Express, the best cards will fit in this slot, with the best options for upgrading in the future. Basically, you can't go wrong with this slot.
5. Some bad cards = Geforce (mx 4000, FX series). ATi (9200,9250, 9550)
I'm not much of an ATi guy, so if anyone would want to add or (gasp

) correct what I have posted please do.
edit, number 1 really should just list the civ4 requirements that have been given to us.
number 2... by testing you mean what? Testing to see if it is good enough? Basically, if you have a good processor (Pentium or Athlon with a high clock like 3.0 or 3000+ prefferably) and at least 512 ram, that should be enough so that your system does not bottleneck due to inefficiency. A good processor, lots of ram, and a good video card (see above) is what it comes down to.
