My PC experience is focused on performance. My PC can handle extremely taxing things, but I'm a framerate whore so I need the best performance I can squeeze out of my system. I reinstall Windows monthly, make registry and services.msc tweaks, and much more. (I am running Windows 7 Professional N SP1 Build 7601, btw)

So with that said, here's my list of installed programs. Share yours!

Winamp v2.00 (1998)
Steam
7-Zip 2.03 (2002)
Advanced SystemCare 7 Pro
Google Chromium (2004)
Latency fixes


Software I have removed from my PC:

Internet Explorer
explorer.exe (the desktop itself)
Power (battery management)
Ethernet detection (I have great wifi)

Share your favorite software and system setups!
