Something's wrong with the 9800GT. It should be about equal to the 8800GT.
Also, nice job posting "Even the low-end GeForce GT 220 graphics card is dramatically better with such workloads than a GeForce 9800GTX" right after the test where the 9800GTX scores almost 2500 and the GT220 "blows it away" with less than 550. Seriously, the GT220 beats the 9800GTX in only two tests. What did you mean?
