This is my first ever build, no more ordering overpriced pre-builts for me! This is primarily gaming/web-surfing/everyday use. My old computer couldn't handle games I wanted to play on even their lowest settings (Metro 2033, Arma 3 alpha) and even L4D2 was playable but still not that smooth. Now it handles all of them like a champ on high settings.
*11/9/13 free upgrade to a 7970 from 7850 (gift from someone I know in the vidya industry). This bumped the Windows Experience rating for graphics from 7.5 to 7.9 (hell yeah). The card is directly from AMD Radeon so I just chose the manufacturer model it looks like the most.
