If you're new to the DIY PC scene, congratulations, you got to skip right over the era of expensive parts. Need an example? In 2006, the going rate for 1GB kit (2x512MB) of performance DDR2-1066 RAM was around $250. Egads, right? This hobby is much more accessible now, as evidenced by today's top deal for an 8GB kit (2x4GB) of G.Skill Ripjaws DDR3-1600 for $50 with free shipping (normally $75). At that rate, you might as well pick up two kits. These modules come timed at 9-9-9-24 and sport custom heatspreaders.
