How good are these cards?

CHAINTECH Geforce FX5500 256MB DDR AGP 4X/8X Video Card - $62

SAPPHIRE LB Radeon 9250 256MB DDR PCI Video Card - $62

POWERCOLOR Radeon 9550 256MB 128-bit DDR AGP 4X/8X Video Card - $64

I´m looking for a card as well. I´m going by the reviews here that these are decent cards for the price, but some expert opinions would be appreciated.
