[H] wrote a ETQW performance guide. They took a close look at how the game performs on today's hardware. The tests:

We are going to keep the in-game settings, resolution and AA/AF at the same levels and compare in an “Apples-to-Apples” manor. This is being done so that we can see how GPU performance scales. Then we will compare the highest-playable settings with an included table of all the video cards tested here comparing. We will then dive into image quality comparisons. All of this is being done under Windows Vista x64.

In the conclusion: "ETQW performs excellent with some of the best graphics available in a video game."
