Look like your video card is the limiting factor here. May want to check that you have the latest drivers for your motherboard too. That may help your performance. And also use the 12.xx drivers from nvidia. They alone gave me a 200 point boost in the benchmark.
Also, using 98lite increased the benchmark by another 100 points, but I'm dual booting win 98 and win 2k, so I don't care about having Internet Explorer in 98
