Options that can help increase performance include:
64-bit, multiple-core processor (for best performance, up to six cores. The extra power is especially important if you use multiple or high-resolution monitors which require more power).
At least 4 GB of RAM, more if you use Photoshop at the same time.
Fast hard disks, especially for the catalog and previews.
