Much differance with 32Meg or 16Meg G400 card?

[London]

I have a Celeron 400 with 128 Megs at 66Mhtz. And a G400 16 Meg version.

I'm running Unreal tournament and it slows down when things get heavy. I also see my hard drive light blicking like crazy. But if I have 128 Megs...why is it running off the hard drive so often? Do I need more Rams? Or would a 32Meg version of the G400 make a differance?

Thanks in advance.

If you are going to play games at 1024x768 32bit color then u need 32 meg otherwise the difference is small even at 1024x768 16bit color.

Unreal is a memory eater, u need around 196 mb to run smooth, or you can increase cache size in settings to help if you already have 128 mb.
