just watch out Tom's Hardware are know to be ATI biased.
Just my 2 cents, a 6800GT owns a X800XT.... the 6800GT also has PS3, something atis X800 range dosnt support.
oh i did'nt notice it said agp but don't worry the differance between APG and PCI-e is basically nothing yet because those to card did'nt even use the full speed of an AGP port.
