Nice one but IMHO definitely over sized.
There is no game that uses all of this resources at the moment. I bet one of this components will die before there is ONE game out there that does. My rig is a Core2Quad, 4 GB RAM and a nVidia GTX 560 GT from Gainward.
Average - CPU usage is 50% max; - Memory usage 2GB
Btw the 4770k (3,5 GHz) is not the fastest CPU of this family. The 3930K (3,2 GHz) has way better benchmark results: Intel Core i7-4770K @ 3.50GHz Average CPU Mark Description: Socket: LGA1150, Clockspeed: 3.5 GHz, Turbo Speed: 3.9 GHz, No of Cores: 4 (2 logical cores per physical), Max TDP: 84 W Other names: Intel® Core i7-4770K CPU @ 3.50GHz CPU Launched: Q2 2013 CPUmark/$Price: 31.48 Overall Rank: 18 Last Price Change: $323 USD (2013-06-04) 10169 Samples: 340 Intel Core i7-3930K @ 3.20GHz Average CPU Mark Description: Socket: LGA2011, Clockspeed: 3.2 GHz, Turbo Speed: 3.8 GHz, No of Cores: 6 (2 logical cores per physical), Max TDP: 130 W Other names: Intel® Core i7-3930K CPU @ 3.20GHz CPU Launched: Q4 2011 CPUmark/$Price: 21.55 Overall Rank: 10 Last Price Change: $560.99 USD (2011-12-01) 12087 Samples: 852
