Part 1 – Selecting components

In this article I will explain how to build a top-spec gaming PC   You should have some experience of PC building  This article isn’t intended for those that have never done it before.

Choosing the case and PSU

When building PC’s, I generally Antec ATX cases, as they are top quality, have lots of drive bays and plenty of cooling. They’re also among the quietest cases around. For this article, I recommend choosing the Antec Three Hundred gaming case. It’s a firm favorite among gaming PC builders for the reasons mentioned above.

These cases don’t come with a power supply these days, so unfortunately you’ll have to buy one. I recommend Antec’s own EarthWatts power supply range, as they’ll easily fit the case, are very queit and reliable.

Antec 300 price around £42.00 from

Antec 650W Earthwatts Platinum PSU £86.29inc. vat

Choosing the Processor, RAM and motherboard

Personally, I always select the CPU first, this will determine the motherboard type. For this article I recommend the Intel Core i7 3770K 3.4GHz Socket 1155 8MB Cache Retail Boxed Processor.

The faster the clock speed, the better the performance, naturally. But there’s much more to current processors than clock speed alone, such as number of cores (4 in this case) hyper threading, virtualisation technology. the Intel ix series processors generally now include Intel graphics actually on the chip itself, rather than on the motherboard. But as this is gaming PC, we will be adding a high performance graphics card later.

You could opt for lesser spec processor and over-clock it, but I have been a fan of this as it can cause overheating and shorten the life of the CPU.

Price £248.63 @


 RAM – Memory
The Core i7 processor requires DDR3 memory. I advise using Crucial RAM. They gaurantee it to be compatible if you use their selector. Memory can be very finicky if not exactly the right specification. I have always used Crucial RAM for years when building PC’s and not had issues.
Asus are my preferred brand, as they are quality motherboard, with good specification and a firm favorite among PC builders. The motherboard I have selected is the here is the Asus P8Z77-V LX Socket 1155 VGA DVI HDMI 8 Channel Audio ATX Motherboard.
£89.75 inc vat @
Graphics card
Here you have a choice of either ATI or Nvidia GeForce GTX 680 or the AMD Radeon HD 7970
Hard drives.
SSD drives are the in thing at the moment, but storage capacity is rather limited. I would still personally opt for a traditional hard drive, unless an SSD drive was to be used as the main drive for Windows and a second normal hard drive added for increased storage capacity. I would recommend a Seagate Barracuda 1TB7200 rpm S-ATA drive, as this will give good, quiet performance, with great reliability. I always prefer Seagate drives when building systems as they are the least trouble. I have had drives of other makes that have failed after not much use!
Optical drives.
DVD-RW burner
No system is complete without a DVD-RW burner these days. DCD-RW burners are mega cheap now, usually around £20 for a S-ATA DVD-RW.
Operating System
My preferred choice of operating system for a gaming PC is Windows 7 Home Premium. Windows 8  is currently emerging bu for now I’ll be sticking with Windows 7.
Where to buy
I use several places when purchasing PC components, namely, or Scan computers.
With these features you should have a top of the range gaming PC reasonable amount of money, and quality components.
