HI! Few days before I bought new video card, FINALLY!!!
I searched for TI cards a lot of time, but it already out of market (at least, I didn't find anyone). So at the end I bought the ABIT's nVidia GeForce FX 5200 128 MB card, it cost me only 100 $. I also bought new hard drive, Western Digital 80 GB 7200 rpm 8 MB buffer.
So now I can even play Need For Speed Underground, GTA 3, Homeworld 2, Hitman 2, and other games smoothly at highest resolutions!!!
Anyway, It is a Great feeling now, to play Great games on this, pretty old computer!
And thank you all for help!
