Fairly old but still handles the job well!
Phenom II X4 965 3.4GHz BE + Stock Cooler (not OC'd until i get my aftermarket cooler)
HD 5770
4GB ddr3 ram
500 g- who cares about HDD size anyway
Proxima Wireless receiver for XBOX 360 (up to 4 controllers)
Running Dishonored on almost everything maxed @ 1920x1080 on my TV
FPS ranges between 45-110 throughout the game
Skyrim stays around 60, GTA IV around 40-70, any Source engine game over 100, borderlands 2 45-80, BF3 30-55 depending on the online map
Temperatures do reach just above the limit for my CPU (62 degrees Celsius) because of the shitty stock fan, but any one under 40 quid should knock that down to a comfortable range soon
Will OC to 3.8 once i get the fan
