Why is it that ATi's new 3870 series completely whip Nvidia in specifications, but they just can't seem to beat Nvidia's 8800 Ultra? Is it a driver issue with ATi or is their hardware design? Nvidia has 128 unified processors; ATi has 320. Nvidia's core clock is 612; ATi ranges in the 700's. Nvidia's mem clock is 2000MHz; ATi's is 2400MHz. Why isn't ATi winning with these cards? They should be.
