Gaming Performance:
The two SLI systems obviously perform faster than the single card machines. The Evesham Quest A620 was slightly slower than the Rock Xtreme CT, despite having the same video card installed.
The Evesham Quest A620 and Rock Xtreme CT performed the same in this title - SLI appears to be CPU limited at 1280x1024.
Finally, the Quest A620 performs the same as the Xtreme SL in Doom 3 when the rock machine is running in single card mode.
Native Resolution Gaming:
Here is a summary of what you can expect from the system when its running at its native resolution of 1680x1050.
F.E.A.R. We found that we had to lower the in-game details slightly to make the game playable at 1680x1050. We were unable to add anti-aliasing, and we had to lower volumetric lighting, water detail and texture resolution to medium. All other settings remained at their maximum. With these settings, we achieved an average frame rate of 37 frames per second, and a minimum of 11 fps during our Heavy Resistance manual run through.
NFS: Most Wanted: We were able to play the game with maximum details, but we had to turn anti-aliasing off to attain a reasonably smooth frame rate. At these settings, we achieved an average frame rate at 37 fps and a minimum of 15 on the NFS: World Loop track.
Doom 3: We were able to maintain a smooth frame rate in this game with the anti-aliasing and anisotropic filtering set to 4x and 8x respectively. We also set the game detail to 'high quality' for our Caverns manual run through. We achieved an average of 54 fps and a minimum of 31.
