Intel Xeon E5-2690

The Intel Xeon E5-2690 packs 8 cores and 16 threads. 16MB of L3 cache helps in cache-sensitive games and workloads. It drops into the LGA2011 socket with a 135W TDP — about 16.9W per core. Clocks run from 2.9GHz base to 3.8GHz boost. Board socket comes first when pairing parts — after that, make sure your cooler's rating covers the chip.

Its $249.95 price tag places it squarely in mid-range territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest processor deals from multiple stores.
