Video cards, a pitiless market

ATI and NVidia war has gone ferocious. It would seem every means is allowed to win over the other, even unfair ones. Otimized drivers would artificially increase benchmark softwares results, and now overclocked cards for the press...
Hence the Radeon X800 tested on various Internet sites woudl have been overclocked by ATI. Yet NVidia would seem to have done the same with their Geforce 6800.
So, the tests to be done in true life environment with commercial cards would probably give inferior results, save for those who'll manage to realize as good overclocking as those - factory made - on specially designed products.
