This is my first custom build completed in March 2013. I wanted something that could handle modern MMOs at max settings and still come in at around $800. Overall, I'm happy with what I got for the money I spent. With the GPU overclocked under normal loads I'm seeing 60-80 FPS, which drops to about 35 in highly populated areas in most games. Everything has run silently and cool even with only stock fans.
All parts were purchased at the Tiger Direct store in Wilmington DE, which is about 45 mins from my apartment and does not have sales tax. At the time they did not have the WD Caviar Blue hard drives or Tahiti based 7870s in stock.
As this was my 1st build, there were a couple lessons learned and things that, in retrospect, I would have done differently. 1. 16GB is way more RAM than I need, though I did get a pretty good deal on what I bought. 2. At the time I thought all PSUs were more or less the same. The one I got is bigger than I need and not 80 PLUS. 3. I didn't plan for cable management when I got the case and should have gone with one that has room behind the motherboard to route everything. 4. The money I could have saved by being smarter with a couple things probably would have let me afford a more powerful GPU.
