My main rig. General purpose so ill break down by category
Gaming: LoL, Batman Arkham AO/AC, Warframe, Hawken, Metro LL, Diablo 3, GW2, and some others Media: Handbrake, ffmpeg, photoshop (actually all of CS6), playback via VLC, PLex Media Server (will soon move to server) Office: Office 2013, Acrobat XI
and of course general use. I sometimes use VM's for testing but will be moving that to a server soon as well.
Single monitor at 1080p and most games play at full settings 60fps or better, some like Batman dip under 60 but it isnt noticeable to me during game play. I bought most of the parts the day haswell released, at which point there was no 700 series geforce cards.
All in all, extremely happy with the rig. Great balance of price and performance. In the near future i may replace the PSU with a more efficient one and then sleeve the cables to make it look nice. Highly recommend all the parts i have in the build.
