The FIC AZ11EA has the Via KT133 chipset with 200front side bus so basically Thunderbird CPU's upto the 1.4 (200fsb version) 4x AGP slot, SDram
Because of the motherboards age, memory type and older AGP bus version, any modern performance card is going to be seriously bottle necked by this platform, you may also have compatibility problems.
My suggestion would be to go for an older graphics card type but one that would have been top of it's range ie:
Geforce 3 Ti500
Radeon 8500
GF4 4200Ti
Most are still more powerful than modern, lower end cards but obviously with less compatibility issues.
a Geforce 3 Ti500 for instance will soundly outperform a geforce FX5200 in most games.
Look on somewhere like ebay where these cards are still available refurb OEM at knock down prices.
