It's quite clear that the GF2 GTS is leading the pack. The GF2 256 DDR takes a comfortable second place at the HQ and MAX settings. It boils down to a battle between the GF 256 SDR and the MX especially when above the Normal settings. It's interesting to note that the SDR falls behind the MX at lower resolutions and then suddenly surges ahead of the MX at 1600x1200.
In the much more demanding quaver demo it's still the GF2 GTS, which is the star performer. The GF 256 DDR keeps pace with the GF2 GTS to a respectable margin. Though the MX performs better than the GF 256 boards at the normal settings, it starts falling back at higher detail settings. Sad but true!
