Performance in Strategies
Age of Empires 3
As we could see in previous test sessions, graphics cards with more pixel processors on board have an advantage in Age of Empires 3 . For example, the Radeon X1900 XT delivers almost two times the performance of the Radeon X1800 XT (for more details see our review called EVGA e-GeForce 7900 GT CO SuperClocked Graphics Card Review). And we can see the same again now: the EN7800GT Top Silent and GeForce 7800 GT leave the Radeon X1800XT behind but are themselves slower than the GeForce 7900 GT which has 4 more execution units.
Talking about playability, you may want to limit yourself to 1280x1024 with enabled FSAA on an EN7800GT Top Silent. In this mode the card provides a comfortable frame rate as for a strategy game.
Warhammer 40000: Dawn of War
Dawn of War is simpler in terms of graphical complexity than Age of Empires 3 and both the GeForce 7800 GT models participating in this review allow playing with comfort in any resolutions and with enabled FSAA. The GeForce 7900 GT and the Radeon X1800 XT have somewhat higher average speeds, but this is of no importance here. Note also that the performance of the Radeon X1800 XT may bottom out to below 20fps in some scenes due to the specifics of the game engine which uses stencil shadows and high-resolution textures.
