Both the FX5900 and the Radeon 9800 are fairly evenly matched in terms of performance (barring cheats, optimisations etc). I think it just comes down to other issues now. Image quality is still ATI's realm. Driver compatability is nvidias. Personally, i like the lower noise and heat of the ATI unit and so far ive had no driver problems. As thousands of people are discovering ATIs drivers have come a long way.
