Built this PC after using laptop for more than 7 years. Have many games bought during Steam sales but was unable to play them, or at best, on low quality and resolution with the laptop struggling on heat issues most of the time.
Super Skylake, super expensive compared to the prices in the US, due to the fact this build was not based in the US. Coupled that with weaking of the currency against USD and additional taxes.
CPU Surprisingly, one of the expensive part in this build is cheaper than US-based merchant prices at the time of purchase. At the time of writing, the Intel Core i7-6700K is cheaper than Intel Core i7-5820K in my country.
CPU Cooler First foray into using AIO cooler. Serves well for me. Prefer it over using traditional air-based cooling solution.
Motherboard Entry level premium motherboard by ASUS on the Intel Z170 platform. Serves well for me.
Memory DDR4, 2 × 8GB, 2666MHz, CL15 memory for me. At the moment of writing, running at 2400MHz at default 1.2V with default motherboard's VCCIO (~0.9V) and System Agent voltage. Can tweak it to run at the original advertised speed for the RAM of 2666MHz that requires me to tweak the motherboard's VCCIO and System Agent voltage higher, to ensure successful system boot up.
Graphic Cards NVIDIA over AMD graphics card for me everytime. I don't consider price at this point for graphics card because there is more than just raw performance. Driver stability is one of the main factor when choosing graphic card vendor. Up until today, NVIDIA graphic's driver is better than AMD counterpart, historically. Although AMD is catching up with the driver aspect, it still has more to catch up on, even today.
Storage Samsung SSD all the way. First foray into SSD world was a purchase of Samsung 830 SSD for my laptop. Increases the performance by leaps and bounds.
Additional Western Digital 2TB Caviar Black for additional data storage. Still better than Caviar Blue or Caviar Green drives in the event I decides to offload some games to the HDD.
Power Supply Unit
Don't skimp on PSU. It is the lifeline to the rest of the system.
SeaSonic is the way to go.
Update (Apr/2016): Replaced the PSU since it failed after barely 4 months of using them. Replacement unit came defective out of the box with the external PSU casing deformed on unboxing. Decided to forgo SeaSonic parts and go with Corsair AX860i digitally controlled PSU.
Casing Absolutely loving the Cooler Master CM 690 III ATX mid-tower case. Came with a side window panel.
Monitor Not going for gaming type monitor. Prefer a higher resolution at 2560 × 1440, IPS and DisplayPort input support. HDMI is garbage compared to DisplayPort. Not many company provide DisplayPort as input option. Dell is one of the consistent provider of DisplayPort monitor.
Keyboard Cherry MX Brown mechanical keys for the keyboard. Love it. Not too loud when typing. Good ergonomics. Ability to switch keycaps should I choose to in the future.
Mouse Decided to go for Logitech gaming mouse after previous two Roccat gaming mouse failed on me.
Headphones Leftover from when the time I was still using my laptop.
Overall PC will be used mainly for gaming. Overclocking will be considered in the future.
