If you are looking to build a new computer and have trouble putting together the right components, visit PC Perspective and look at their hardware leaderboard. Click the tab at the top that says "HW Leaderboard" and check out the low-end, mid-range, high-end, and dream system rundowns. The HW Leaderboard comes with recommendations for the proper processor, motherboard, video card, memory, hard drive. sound card, and power supply to get you started on building the type of PC you want. From there, you can more comfortably do your own research on Reddit, AnandTech, and other review sites/forums.
