The Elder Scrolls IV: Oblivion
The only way to keep the limitations of the Core 2 Duo E6850 from being a factor was to enable the filters, except with the 9600 GT and HD 3850 - the only cards that were beginning to saturate with the processor. Antialiasing again proved fatal to the 8800 GT 256 MB, which was out of the race, and to a lesser degree to the Radeon HD. That made the 9600 GT a shoo-in for second place, and in fact it moved very close to the 8800 GT, with only 3 to 9% less performance.
