Best Components for 300 dollar Gaming PC
Here is the list of major components that you will require for a gaming PC under $300 budget. There is no monitor, mouse, keyboard and optical drive but only the major components that you need inside the PC case.
Intel Pentium G4400 @ 3.30 GHz
For a 300 dollar gaming PC you should be fine with a good dual core processor because if you move to quad core or core i series processors then your total budget will go way above 300 bucks. So here I have selected Intel Pentium Processor G4400 which is a dual core processor having maximum speed of 3.30 GHz. It uses the latest FCLGA 1151 Socket and has Cache size of 3 MB. It comes with Intel HD Graphics 510 integrated but we won’t need that because we are building a gaming PC and will use a dedicated graphics card.
Intel Pentium G4400 is the latest best affordable processor that is also big on performance. It is a dual core Skylake processor that consumes lesser power and stays pretty cool even with the stock cooler. You will never loose out on performance in games when your pair a good graphics card with this processor. When paired with a good mid-range graphics card you can play most of the games at 1080p. You may also overclock this processor further for more performance but for that you will require a good aftermarket cooler.

MSI B150M PRO-VHL
For Pentium G4400 Skylake processor you will require a Socket 1151 motherboard. The main advantage of Socket 1151 motherboard is that it this is the newest socket type and is used for the latest Skylake and Kaby Lake processors, and will let you upgrade to better processor in future without having you to change your current motherboard.
Here I have chosen MSI B150M PRO-VHL motherboard which is a very good budget motherboard for Intel 6th Generation (Skylake) and Intel 7th Generation (Kaby Lake) processors. It is a micro-ATX motherboard and comes with decent amount of features. It supports Core i3/i5/i7, Intel Pentium and Intel Celeron processors for Socket LGA 1151.
