I agree with many others here. While "gamers" do play games, they also want a system with some longevity. Such a system would probably have a quad core processor and a single video card. One person gave the example of a Phenom II X4 processor with single HD 5770. A great example.
The author points to a Crisis benchmark with a single 5770 as a counter argument. Well that benchmark shows 34 FPS at 1900x1200 resolution in High Detail. Plenty fine in my book! When more power than that is needed, you can drop a second HD 5770 in there when they get cheap.
A "value" system is not a good value if every component needs to be replaced in 1-2 years. I respect that you guys were going for maximum FPS *right now*, but most of us wouldn't want to build such a system.
