3d mark score, and pixel shade question??

Had problem runnig 3d mark 5, here's the system info.

1.thermaltake 480 watt powersupply
2.gigabyte GA-K8NS nforce 3 board GA-K8NS socket 754
3.athlon 64 3000 socket 754
4.master 80 gig hard drive(maxtor)
5.slave 40 gig harddrive(maxtor)
6.radeon 9800 pro 128mb, 256bit
7.512mb ram

I know this is probally slower compared to some of your guys system but considering before this we were using a pentium 2 350 mgh computer and rdeon rage pro 8mb card. I ran 3d mark 3 and got a score of 5656. None of my system is overclocked because i don't want to get into that right now. I don't know how well that is though. were can i go to compared my scores? I went on the futuremark website but couldn't find the place to check it out. I tried to run 3d mark 5 but it said i need pixel shader 2.0. I thought the radeon 9800 pro had pixel shader 2.0 ??? Well any advise on making this computer run better that doesn't involve overclocking would be helpfull. I using the catalyst CD that came with the video card bye the way and my CPU temps run at 29 degrees celcius, on load And 35 degrees after running 3d mark 3.
