If you want to really get down to work and enjoy the experience, consider upgrading to a system like this (in parenthesis I've also added what I would consider "dream" system components: not required, but the way to go if you wanted to go all out):
AMD 64 3.0 Mhz or Intel P4 3.0 or better (dual processors)
1 Gigabyte of RAM (2 Gigabytes)
160 Gigabyte hard drive (2 drives, each 250 Gigabytes)
19 inch digital (DVI) monitor running at 1,280 x 1,024 32-bit (two 19 inch DVI monitors)
64 Mb NVIDIA® GeoForce® or ATI® Radeon® graphics card (256 Mb with support for two DVI or VGA monitors)
