The Tech Report has posted a system builders guide with recommendations for the righ enthusiast's PCs.
WE GET A LOT OF REQUESTS for system and component recommendations. Everyone's looking for the best bang for his buck, either for individual components or complete systems, and we've played with, benchmarked, and otherwise abused enough hardware to know what's what. We've even dedicated an entire forum to vetting system configurations. Although our System Builder's Anonymous forum is a great resource for those looking for opinions on prospective builds, the time has come for an official system guide from The Tech Report.
HardOCP also posted one, altough they focus on upgrading system with $500-$1000 and building new systems for $1200 to $2000.
As is our standard, we strive to provide foundation systems that can provide some upgrade room in the future. It is not uncommon for our own systems to survive one or two upgrade rounds before every component is replaced with new. This allows us to stretch our buying dollar well into the future by leaving room for upgrade paths for CPU, memory, or video cards without buying an entirely new system. We also want to give readers a look at the kind of components we’d spend the money on; these are all parts we’ve used in one system or another.
