About 8 months ago, I built my first PC for ~$400, I recently sold that without my hard drives for a $115 profit, with the $415 I got from that and some additional $300 I had, I built this beast which has some great parts for a relatively low cost. I am mostly using this for games like CS:GO, Battlefield, Far Cry, GTA, and for future AAA titles that will be coming out soon like Mafia III. I plan to be able to max them out on my 1080p monitor while having 60 fps, and maybe getting a 1440p monitor in the future. I built this with everything except for the graphics card and I planned on waiting for a 480 or 1060.
Processor: I knew I would need a quad core for most games, I didn't go with the 6600k since I didn't want to pay more for a better motherboard to overclock with, so far very satisfied for gaming and some small video editing. Always nice to have the newest Skylake architecture.
Motherboard: One of the cheapest Skylake motherboards out there, I didn't need any crazy features since I am only having one gpu and no need to overclock. It has a decent bios and it gets the job done.
Memory: Thought it was a great deal to get 16gb ddr4 for under $50, not a well known brand but it is just ram so I should be fine.
Graphics Card: I was on integrated graphics for nearly 2 months, GTX 1060 AIB cards came out and I got a good deal on mine with a $25 off code. This is a great graphics card and has got some great features. I easily max out all games on 1080p. It has rgb lighting, a included backplate, great cooling, and great performance. I don't think I should have any trouble with games for a while and I have been very pleased with this purchase.
Case: I really love this minimalist look on this case and the white goes along with my setup, this case is made out of solid materials and many things make this case feel very high end. Good cable management and the power supply both made the build very easy, very good case from a great brand.
Power Supply: I saw this on sale at Best Buy and decided to pick it up, I didn't have the budget for a modular PSU and I thought this was a good deal. The fan is very silent and I have had no problems with it.
Case fans: I had the stock fans in but I really like all be quiet! products and having pwm fans, I saw they were on sale for $10 a piece and had to get them. They have been basically silent and I have been very pleased with them.
