Yeah.  NVIDIA dropped support for that one a long time ago.  I think 
Isaac and Jarod were suggesting a new video card, not a new driver.  You 
should be able to get a GF4MX440 or (even better in case you ever do 
HDTV) a GF5200 for $40 or less.

I'm guessing that "no way out" means it's not a usable solution.  If so, 
I'd agree (and say that a new graphics card is the solution).

You can change:

Guide Shading Method
    * Alpha - Transparent (CPU Usage - High)
    * Blender - Transparent (CPU Usage - Middle)
    * Eco - Transparent (CPU Usage - Low)
    * Solid (CPU Usage - Middle


CPU friendly preview of recordings
When enabled, recording previews will play with reduced FPS to save CPU.


Use Transparent Boxes
If enabled, the Watch Recording and Delete Recording screens will use 
transparency. Disable if selecting the recordings is slow due to high 
CPU usage.

But it probably still won't help enough for that card/driver combo.  I 
would say spending $40 ($20 with a good sale) for a better graphics card 
is a better idea.  (And, if you're not in the US and can't get the card 
for a reasonable price, I can't suggest any cheap alternatives.)
