NVIDIA GeForceFX 5900 Ultra: The Way FX is Meant to be Played!!

4xFSAA & 8x Aniso

This is the highest comparable quality setting. ATi's Radeon 9800 also supports 6xFSAA as well.

At first the FX 5800 Ultra is able to keep up with the Radeon 9800 PRO until we reach 1600x1200 where its performance drops off quite sharply. The FX 5900, on the other hand, takes first place in almost all resolutions, obviously benefiting from its huge memory bandwidth of 27.2 GB/s (ATi Radeon 9800 PRO: 21.8 GB/s). In 1600x1200 we can see the same fallback than in 4xFSAA.
