Suggestion
mobo: ASUS brand
>chipset: if Intel, go for X79 for LGA 2011 or Z87 for LGA 1150
cpu: if intel, go for LGA 2011 or LGA 1150. Based on statistic on Intel marketing, LGA 1155 will be discontinued next year, LGA 1150 will be discontinued 2016, and LGA 2011 will be discontinued by 2018. Use this as a guideline so you know if you cpu will be discontinue soon
AMD is cheaper, but not as good of a performance than Intel. Intel is built for everything. I don't use AMD cpu so I can't give you suggestion on that
cpu cooler: If intel, go aftermarket cpu cooler like Corsair H60 (cheap and great performace) or Hyper 212 plus is great since Intel cpu (i5 or i7) tends to get hot really quick
ram: Corsair DDR3 8GB should be enough for gaming. If you use virtual machine like VMware, go for 16GB.
Video card: Market price always changes, but for now, I say go for Nvidia card. AMD is very good, but due to bitcoin, everyone is buying AMD card for bitcoin mining, so price has jump super high. For example, I bought Asus R9 280X card for $309 USD when it was new and it has jumped to $600 USD (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121803).

SSD: If you want, 120GB Intel, Samsung, or Corsair should be enough for OS and any other software. Games will need to be installed on a secondary drive
> Intel - Most reliable
>Samsung - Fastest
>Corsair - great, not best
Optical drive: If you don't mind, I say get blu-ray since it is a matter of time before all media will be released on blu-ray. However, dvd is always good.
Chassis: mid-tower or full-tower, but note cpu cooler like Hyper 212 Plus might not fit in a mid-tower chassis
