The XPS M1730’s powerful processor pushes it ahead in Oblivion’s cave scene, but the system won’t run the game at the panel’s native resolution.

In Oblivion’s outdoor scene, the XPS M1730 is playable at 1280x1024 pixel resolution, while the Area-51 m9750 is limited to 1024x768. Once again, the XPS M1730 didn’t run the benchmark at its 1920x1200 native panel resolution, but even if it could, the frame rate would be unplayable.

Dell XPS's are nice, but to be fair the application performance is irrelevant. The huge cost of these are only justified by the gaming performance.
In this the Low Res gaming, doesn't matter a toss either. Alienware probably have better build quality. Do you notice as well that only the dell got the look inside and out. Biased article. If you have a choice never buy dell.
I don't understand why you would bench compare the two machines with two different operating systems. This make the whole comparision between them very inaccurate.
At least use the same os configuration if you want to compare benchmarks between the two.
A very unprofessional article.
