Performance in RPG
The increased clock rates help the Zotac win the test at 1920x1200 but the Radeon HD 4870 X2 remains superior at 2560x1600. The Zotac has a somewhat higher bottom speed, though, which makes the cards equals in a gamer’s eyes in terms of performance.
The Elder Scrolls IV: Oblivion
The game loses much of its visual appeal without HDR. Although some gamers argue that point, we think TES IV looks best with enabled FP HDR and test it in this mode.
The Zotac is hardly any better than the reference card. You cannot feel this in practice considering the high frame rate of every card. The only real advantage over the Radeon HD 4870 X2 is that the Zotac has lower fluctuations of performance in open scenes at 2560x1600 but the reference GeForce GTX 280 can boast the same.
