I don't get it why should their products (regarding video cards) would be inferior to any other company in terms quality? Almost all the 7800 GTs for sale use the same heatsink, PCB, GPU, etc. supplied by nVidia, why should initial quality be affected at all? Maybe customer support is less than that of other companies (personally I wouldn't know, never owned a Chaintech video card), but to say they have inferior products seems ignorant.
And to say Epox and Thermaltake have a good "name" I'm not sure I agree, especially in regards to Thermaltake.
