High Quality AA and AF
Our high quality tests let us separate the men from the boys and the ladies from the girls. If the cards weren't struggling before they will start to now.
Far Cry 2
The HD 5850 struggles in Far Cry 2 with AA on, so it comes as no surprise that the HD 5830 has the same issue. The overclocked card here, though, again from MSI does offer us a boost in performance.
Resident Evil 5
Under RE5 we see that both cards sit perfectly in line with each other at 39 FPS.
Tom Clancy's H.A.W.X.
H.A.W.X. sees another 1 FPS bump, but nothing that you're going to get excited about.
