I have been running Windows 2000PRO SP2 system for the past 3 months.<br> I have done about every tweak as much as possible except overclock.<br> My stock 3dmark 2001 scores were 5183. I knew it could get faster even for a system with PC133 memory.<br> <br> I just recently installed XP Pro, ran the Microsoft updates, installed<br> 23.11 drivers and installed 3dmark 2001. My score is now 6233 which is about right for this system. <br> <br> My next two tests will be to do a clean install of Win98SE and Windows 2K pro to see what the scores will be.<br> <br> Here's my system:<br> <br> Tyans2390b bio 1.10<br> Athlon XP 1600<br> 1gb PC133 SDRAM (Crucial 2x 512mb)<br> XP Pro <br> 23.11 dets<br> Visiontek Geforce 3TI200<br> <br> derekn
