I use this rig for gaming, movies, and basic internet browsing. I have the CPU overclocked at 4.5GHz on air cooling 24/7 with no problems. Incase anyone was wondering, it's an i7 3770k on an Asus Sabertooth Z77 mobo with a multiplier of 44, CPU voltage of 1.33V, stock BCLK Frequency of 103.0MHz, and stock DDR Voltage of 1.50V. I was able to fit 5 200mm, and 2 120mm fans into the fairly large Cooler Master HAF 932 tower. My most prized possession is my monitor. Asus's recent release of their gaming monitors are superb. The VG248QE which I have has a 1ms trace-free response time, 144hz refresh rate, nVidia 3D Vision ready, LED backlit, and includes a 3-year warranty. Without a doubt this monitor gives me the smoothest gaming experience I've had.
