General purpose desktop computer

These days, $500 to $1,500 will net you a desktop with a dual-core CPU and enough power to run productivity apps, view and edit vacation photos, manage MP3s and videos, and even play many of today's games--the core activities most common to families, students, and the general purpose PC user. At $1,000 and up, you should easily be able to perform those tasks. Spend around $500, and in most cases you'll still be able to run common tasks without delay, although 3D gaming becomes a stretch. You will definitely find a dual-core chip in a $500 desktop (you should insist on a dual-core chip these days, unless your budget keeps you under the $500 mark), but Vista could still give you trouble. Be sure the PC is equipped with at least 1GB of memory, and it's a good bet that you'll be able to smoothly run Vista. Add in a 128MB graphics card, and you'll get the Aero effects with little to no performance loss.
