Ok, Hiiro. First, make sure you have an AGP slot (dunno if I am speaking to a complete noobie, but ill continue anyway).
If you are gonna upgrade your video or build a new computer, make sure you have an AGP slot. It is a brown slot that normally is above the white PCI slots.
Now, if on a budget, I recommend at least a GF3 ti500 or higher. I have the origional GF3, and Doom III alpha runs terrific. Imagine how it would run on a ti500.
Here is a good deal on one:

Now, if you are going for a performance, I recommend a Geforce4 ti4200 if you want a little more kick to your gaming, or a ATI Radeon 9500 pro if you want serious performance.
*edit* Found a great price on a 9500

I hear some nice things about GeforceFX, but Jason Xero says "nope". So I'll take his word...
