PixelSearch function

[mark2004]

I hope this is not a stupid question but I need to know what PC hardware is most responsible for running the

PixelSearch function. Is it the CPU, RAM or Video Card?? I have a script that uses alot of pixel-related functions

that runs fine on my PC but struggles badly on a client's pc. I'm just trying to figure out what I need to upgrade in

order to get the script to run quicker.

Thanks.
