AMD HD6790 Review
Alien vs Predator
AvP is a lot kinder. Although out of the box it struggles to pass the bare minimum 30 FPS average, at least with the overclock in place it has a little more get up and go.
Things are very similar in Crysis Warhead. Obviously for a low-end card we're running only at Gamer settings and zero Anti-Aliasing but still the HD6790 manages a healthy 40FPS. Despite only grabbing 4 more frames from the overclock the most important thing is the big leap in minimum frame-rate which helps reduce the stuttering as the card tries to keep up.
We did run in maxed Enthusiast mode but an average of 20FPS isn't desirable to anyone and if you wanted to run in those conditions you shouldn't be looking at such a basic graphics card in the first place.
