Build-It: The $800 Gaming PC
 

This time we're going to be even more aggressive on price, giving ourselves $800 to build out a PC that can get the job done when it comes to games. Naturally we'll try to make it a system that is useful for other general PC tasks as well--it's not like we're going to forgo a CD burner to save a few bucks just because burning CDs isn't necessary for game performance. We're also going to cheat a little bit: $800 is almost too low a price to make a truly acceptable gaming PC, but our price won't include monitor or speakers. Most users have holdover monitors or speakers from their current systems, and when your budget is $800, reusing them with your new rig is a very real option.
