WIN2k reallly Slowwwww with p3v4x... HELP!!!!

[Phasis 0]

I have recently put Win XP on my system and I have only come to realise how slow win2k is in gaming. In 3dmark 2001, I got 730marks 1024, 16bit. In Win XP, this score went to 2400marks.

Likewise, in Counterstrike, win2k's framerate will only hit 60fps (refresh rate) when I look into a corner, and can drop to below 20fps, In XP, most of the time it's at 60 and only drops to about 30-40 in heavy fighting and smoke.

I have the following system.

 

Win2k, 4.29 via drivers

Win XP b2462, packages drivers,

C2 566@850 1.7v Arcticooler

Asus P3V4X 1004 bios

256mb PC133

Leadtek GF2MX 215/205 7.52 driver

IBM DESKSTAR 75GXP 45GB

Quantum 10.2GB CX

36x CdRom

2x 3com 3c905b

Alcatel ADSL Modem-Bigpond

 

Is there a way to install the mobo drivers from the XP partition/cd into win2k seeing as XP is built on Win2k?
