I've been building PCs for the last few years, repairing laptops as well.
Overall I've done a lot of AMD CPU based builds but for the past year Intel CPUs have found a permanent place in my heart. On the GPU side I've mostly preferred nVidia, beginning with GeForce 8600GT up until now having my ASUS STRIX GTX 970 inside my own latest build. Right now I also have 8GB DDR3 RAM which I plan to upgrade with additional 8GB, a 120GB Kingston V300 SSD, which I hopefully swap for a 250GB Samsung EVO 850, and an Intel Core i5 4690K overclocked to 4.4 GHz. In the future I plan to change it with Core i7 4790K and overclock it to 4.5 GHz - beQuiet Pure Rock cooler should handle it without any issues.
I do quite a lot of gaming - playing mostly Blizzard titles such as Diablo 3 and Heroes of the Storm, also Borderlands 2, Witcher 3, Mortal Kombat, Street Fighter, Battlefield, Crysis 3, Batman Arkham series and many more. Recently I've started uploading a few gameplay videos on my Youtube Channel.
