Performance in Strategies
Age of Empires 3: The War Chiefs
The EN7950GT is far ahead of the EN7900GS Top. The biggest gap between them is in 1280x1024 and 1920x1200 resolutions, 15% and 20%, respectively. The difference is smaller in 1600x1200 for some reason, about 10%. Note also that the huge GPU frequency growth of the EN7900GS Top over the reference GeForce 7900 GS gives it a lead of only 8-10%. This may be due to high load on the TMUs and lack of graphics memory (256MB is too little for this game).
Company of Heroes
EN7900GS Top has not a single chance against EN7950GT, and even higher working frequencies do not help here. In 1280x1024 the lag is about 25%. Together with the low minimal fps rate it doesn’t give us any reason to hope for comfortable gaming experience. At the same time, the performance of EN7950GT is high enough for that, and overclocking provides additional speed reserves.
