as the matter of fact, i have tried everything, but couldnt solve the problem , so my conclusion is that this graphic card is dying/or not suitable for this pc config.
So now, i replaced it with this PC's native one , its WinFast A80B T 64Mb, and its working but i can't find the proper driver for this one on net...

go to producent site http://www.leadtek.com/eng/support/download.aspx and 3d graphics -> agp cards -> find your model ;-] probably some from gf4 series. i cannot find that model what you wrote here ;]

man this was exactely what i needed, now i can run q3 with 1600x1024 resolution with 125 stable fps, awesome thanks mate <3

[edit] now i've got one more problem to solve, and its called "ghosting". when i play i see blurry movements when i make fast moves with my mouse ,and i feel like playing on LSD does anyone knows how can i fix this? i think it has smth to do with monitor response rate.

You probably need to switch the refresh rate of the monitor from monitor settings or VGA settings to the highest possible..

CRT you have??

It could go up to 120 or 240hz in some cases,

CRT you have, lucky you!!

nah ,its LCD and with this monitor and graphic card max refresh rate is 85 with 1024x860 and for 1280x1023 max is 60, and in both ways it doesn't change this ghosting effect that i get in game.
