Hardware for fraps - Minimum/Recommended

[sourjo]

So I have been wondering about this for some time.
I used FRAPS for my first movie earlier this year http://video.google.com/videoplay?do...44840243324943

As you can see I have big problems with the fps.

My current hardware is:
2 GHz AMD Athlon XP
1 GB DDRRAM 333 MHz
400 MHz FSB motherboard
nVidia 6600GT AGP card
Creative SoundBlaster Live!
And I was capturing the video on my Seagate USB 2.0 100 GB external hard drive (5400 RPM)

What is the minimum hardware I would need to capture video with decent fps. And at a resolution of atleast 800x600. What would I need for higher resolutions? 1024x768? I used the external hard drive because someone said I shouldnt be running the game from my internal hard disk and capturing on the same disk.

Also, for those of you frapsers who have been doing it for a while and getting good fps, please post your system specs.

I would appreciate any replies. I am sure there are other machinima noobs like me who could benefit from this information
