As a first time PC builder, I had a lot of fun building this machine. The build took around 3 hours, and assembly and OS installation all went smoothly. I currently use it for gaming and a little productivity. I don't have the full version of 3DMark 11, so i can't provide Entry & Extreme Preset Scores. As for other benchmarks, I get around 90 fps in Battlefield 4 on ultra preset, and I'll add more benchmarks when I get the chance.
