So I saved about $150-200 total doing this build, all things considered. The 6870 is working like a dream, which I'm so pumped about, since I was worried about using a year-old part. Also I was adamant on using AMD for this build, and so far it's paying off in spades. Running my FX-6300 at stock speed is getting me WEI scores of 7.5, which I'm impressed by, given my ability to add in a little simple overclocking down the road if I want to.
I chose Windows 8 for this build for two reasons. 1: because I got the DVD for christmas and I couldn't complain, and 2: because I chose not to get a boot SSD, and wanted fast boot times. From a cold boot to the login screen takes 14 seconds booting from a 7200RPM hard drive, and with Start8 installed, everything feels like Windows 7, but with neat desktop apps, and a cleaner, much faster interface.
Building was somewhat of a breeze. Aside from the CPU fan mount issue, nothing really went wrong. Really, I'm just waiting for something to break, but for now, I'm redownloading all my steam games like a mofo and moving my life onto my brand new, fast and smooth desktop
Also, as for the tiny cramped space, I'm sort of in transition right now between living arrangements, and don't have much room, but the monitor is now taking up the space where my laptop once was in the build pics. Will probably post a nice battlestation picture in due time.
