Call of Juarez
The in-game benchmarking tool does not support 2560x1600 resolution so we had to limit our test to 1920x1200.
The Zotac card can’t compete with the dual-processor Radeon HD 3870 X2. The latter can yield an average frame rate of over 25fps as none of modern single-processor cards can. The overclocking effect is small in this game, hardly above 1%.
Call of Duty 4: Modern Warfare
The factory overclocking has a stronger effect in this game. It adds 8% to the performance of the reference GeForce 9800 GTX at 1280x1024. With this addition, the Zotac is 26-27% faster than the GeForce 8800 GTS 512MB. Now it looks like a flagship G92-based solution indeed.
The performance increase is smaller at the higher resolutions, though. It is also insubstantial in absolute numbers to affect your gaming experience. The GeForce 8800 GTS 512MB provides the same level of comfort at 1920x1200 as the Zotac card does.
