With or without antialiasing applied, these two gaming juggernauts show what amounts to a tie when it comes to Prey. The Reactor shows a very slight advantage when antialiasing is turned on — perhaps due to the 8800 GTX’s higher memory bandwidth — but the advantage is more theoretical than practical.
The Reactor shows a more noticeable lead when it comes to lower resolutions in Quake, but once again this advantage is too slight to notice in real-world gaming.
Serious Sam 2 shows us more of the same, with the exception of the iBuypower taking the performance lead once antialiasing is applied. Still, it is a small advantage of no real-world consequence.
Supreme Commander shows us some curious results, and the first real notable performance differences in the review. Notice how the Reactor’s high clock speed allows it to attain higher frame rates at lower resolutions; when the resolution is increased, the frame rates on the quad-core 942IL remain fairly constant, yet the dual-core reactor drops off significantly. We know that Supreme Commander is probably the most CPU-hungry title out there, and this is likely the cause of this phenomenon. The actual frame rate differences are still quite minimal between the two systems, however.
Warhammer doesn’t appear to be as multithreaded as Supreme Commander, preferring the higher clock speed of the Reactor at all resolutions.
